 into  the  Future   Steven  French  and  Michela  Massimi     Steven  French   School  of  Philosophy,  Religion  and  History  of  Science   University  of  Leeds     s.r.d.french@leeds.ac.uk     Michela  Massimi   School  of  Philosophy,  Psychology  and  Language  Sciences   University  of  Edinburgh   michela.massimi@ed.ac.uk       Abstract:  In  this  opinion  piece,  the  authors  offer  their  personal  and  idiosyncratic  views  of  the  future  of  the   philosophy  of  science,  focusing  on  its  relationship  with  the  history  of  science  and  metaphysics,  respectively.   With  regard  to  the  former,  they  suggest  that  the  Kantian  tradition  might  be  drawn  upon  both  to  render  the   history  and  philosophy  of  science  more  relevant  to  philosophy  as  a  whole  and  to  overcome  the  challenges   posed  by  naturalism.  When  it  comes  to  the  latter,  they  suggest  both  that  metaphysics  has  much  to  learn   from   the   philosophy   of   science   and   that   it   offers   an   array   of   tools   that   philosophers   of   science   can   themselves  appropriate.     Keywords:  Kant;  metaphysics;  philosophy  of  science.       Philosophy  of  science  is  entering  a  new  exciting  era.  As  the  editors  of  the  British  Journal  for  the  Philosophy  of   Science  (BJPS),  we  witness  an  enlarged  horizon  of  topics,  areas,  and  buzzing  interactions  between  philosophy   and  the  sciences  that  the  founders  of  the  journal,  back  in  1950,  could  not  possibly  have  dreamt  of.  While  the   programmatic   intent  of  the  journal   in  the  original  Editorial  was  to  explore  “the  whole  range  of  science— physical,  biological,  and  psychological”  and  take  “science,  both  past  and  present  .  .  .  as  the  primary  datum   for  consideration”  (BJPS  1950,  3  and  4),   it  would  have  been  hard  to  predict  how—some  sixty-­‐three  years   later—the  complex  dynamics  between  philosophy  and  science  would  have  radically  changed  the  landscape   of   the   subject   area.   From   foundational   studies   of   physics,   to   evolutionary   developmental   biology;   from   neuroimaging  and  evolutionary  psychology  to  causal  decision  theories  and  signal-­‐  ling  games:  these  are  just   a  few  of  the  many  faces  of  contemporary  philosophy  of  science.  The  field  has  expanded  in  myriad  directions,   and  has  engaged  in  serious  conversation  with  the  sciences  at  large,  following  the  naturalistic  trend  of  the   second  half  of  the  last  century.  We  could  never  do  justice  to  the  complexity  of  the  current  panorama,  and  do   not   even   attempt   in   what   follows   to   provide   an   overview   of   the   many   intricate   and   alluring   topics   and   subfields  on  which  we  have  the  honour  of  publishing.  The  interested  reader  is  kindly  referred  to  the  table  of   contents  of  any  issue  of  the  BJPS  for  that.   Instead,  given  the  aim  and  scope  of  the  present  contribution  as  an  opinion  piece,  we  have  decided  to   follow  a  more  familiar  path  in  providing  two  personal,  inevitably  incomplete,  and  unashamedly  idiosyncratic   views   of   how   we   see   the   field   evolving.   The   views   are   personal   as   they   reflect   our   respective   personal   research  interests  in  the  field  as  authors,  before  being  editors  (and,  in  fact,  quite  independently  of  our  role     as  editors  of  the  BJPS).  They  are  inevitably  incomplete,  as  the  short  remarks  here  below  cannot  possibly  do   justice  even  to  the  two  chosen  trends  (history  and  philosophy  of  science  [HPS]  and  metaphysics  of  science)   on  which  we  have  decided  to  concentrate.  They  are  finally  unashamedly  idiosyncratic,  because  they  reflect   our   individual   take   on   each   of   these   two   fields.   In   what   follows,   we   take   a   look   in   turn   at   HPS   and   the   metaphysics  of  science,  as  just  two  families  inhabiting  the  many-­‐storeyed  house  of  contemporary  philosophy   of  science.  Although  the  limited  selection  of  subfields  preempts  any  temptation  to  draw  grand  conclusions   about  the  future  of  philosophy  of  science,  we  hope  that  what  follows  may  serve  as  a  spring-­‐  board  for  wider   reflections  on  how  each  of  these  two  areas  has  affected  the  remit  of  philosophy  of  science  as  a  whole,  and  is   bound  to  shape  (at  least  in  part)  its  future.       A  New  Era  for  History  and  Philosophy  of  Science     When  it  comes  to  new  directions  in  the  vast  field  of  philosophy  of  science,  it   is  hard  not  to  mention  the   recent  revival  of  the  trend  that  goes  under  the  name  of  HPS,  or  history  and  philosophy  of  science.  Since  both   of  us  work  on  and  have  made  contributions  to  HPS,  we  have  chosen  it  as  our  first  paradigmatic  example  of   future  directions  in  philosophy  of  science,  with  an  important  caveat.  Once  more,  the  following  reflections  on   the  status  of  HPS  and  its  future  are  just  personal  considerations  from  the  point  of  view  of  our  own  work  in   the  field.  They  are  not  intended  to  be  reflections  about  BJPS  publishing  policy  or  editorial  directions.1   Caveat   aside,   there   is   no   doubt   that   recent   times   have   witnessed   a   very   productive   and   renewed   interaction  between  philosophy  of  science  and  history  of  science.  Far  from  being  a  remnant  of  foregone   times,   when   the   likes   of   Popper,   Lakatos,   Kuhn,   and   Feyerabend   set   out   HPS   as   a   distinctive   discipline,   contemporary  philosophy  of  science  has  explored  promising  new  ways  of  drawing  on  the  history  of  science   to  illuminate  both  old  and  new  philosophical  problems.    Be  it  foundational  issues  about    spacetime    theories     (see,  e.g.,  Norton  1985,  2000,  2008;  and  Howard  1985,  2010)  or  the  science  of  measurement  or  metrology   (Chang  2004;  Tal  2011;  Teller  2013);  be  it  realism  and  anti-­‐realism  about  science  (Giere  2006;  Stanford  2006;   van   Fraassen   2008),   or   the   nature   of   scientific   theories   and   models   (Morrison   2000);   be   it   biological   complexity   (Mitchell   2009)   or   the   evolution   of   physical   concepts   (Arabatzis   2006),   the   many   faces   of   contemporary   HPS   show   how   thriving   the   field   is.   A   new   national   and   international   movement,   called   Integrated  HPS,  to  which  both  of  us  have  actively  contributed  since   its  foundation  back   in  2006,  provide   annual  national  and  biennial  international  gatherings  where  the  state  of  the  art  in  the  field  is  presented.  The   programmatic   manifesto   recommends   more   than   just   the   Lakatosian   dictum   of   a   historically   informed   philosophy  of  science  on  pain  of  philosophy  of  science  being  empty.  Good  HPS  is  not  philosophy  of  science   with  interspersed  case  studies.  Instead,  it  is  both  good  philosophy  of  science  and  good  history  of  science.  It  is   philosophy   of   science   that   brings   history   of   science   to   the   fore   and   genuinely   draws   on   it,   without   any   preconceived  philosophical  agenda.   In  some  philosophical  quarters,  noses  turn  up  at  the   idea  of  philosophy  of  science  drawing  on  the   history  of  science.  For  surely  the  normative  role  of  philosophy  would,  appear  to  some  to  be  impoverished  by   renewed  attention  to  the  history  of  science.  Prejudices  aside,  two  challenges  stand  on  the  way  of  HPS  as  a   promising  direction  of  research:     I.  Disciplinary  enclaving:  we  are  using  a  strong  word  here  to  convey  the  perceived  uneasiness  felt  in                                                                                                                             1  BJPS  publishes  first-­‐rate  articles  in  HPS,  among  many  other  areas,  although  HPS  does  not  constitute  the  distinctive   remit  of  the  journal,  by  contrast  with  Studies  in  History  and  Philosophy  of  Science  (A,  B,  and  C),  among  other  journals.     some  HPS  quarters  of  working  in  isolation  from  the  broader  philosophy  community,  as  testified  by  the   low  presence  of  HPS  papers  at  the  meetings  of  several  main  philosophical  societies,  for  example.  What   good  is  HPS  to  philosophy,  in  general?     II.  Naturalism,  or  when  a  virtue  may  become  a  vice:  that  philosophical  inquiry  should  be  continuous   with  science  is  a  hard-­‐to-­‐resist  tenet  after  Quine.  That  philosophy  of  science  should  engage  with  the   details  of  actual  scientific  practice  is  also  a  sine  qua  non  of  any  credible  inquiry  into  science  and  its   modes  of  inquiry.  But  how  to  walk  the  thin  line  between  philosophy  and  the  sciences?     The  two  challenges  seem  to  be  pulling  HPS  in  opposite  directions.  Any  serious  attempt  to  bridge  the  gap  with   philosophy  seems  prima  facie  to  force  HPS  away  from  its  naturalistic  leanings;  as  much  as  following  those   leanings  risks  transforming  HPS  into  a  series  of  scientific  case  studies.  In  what  follows,  we  selectively  look  at   a  possible  (by  no  means  exclusive)  way  of  addressing  these  two  challenges  in  contemporary  HPS,  namely,   “dynamic  Kantianism.”     How  to  Bridge  the  Gap  Between  HPS  and  Philosophy:  The  “Back  to  Kant”  Recipe     There  is  something  prima  facie  surprising  about  the  recent  revival  of  Kantianism  in  HPS.    For  surely  nothing   would   seem   more   remote   from   contemporary   scientific   practice   than   Kant’s   outmoded   view   of   natural   science.  Why  hark  back  to  Kant  and  neo-­‐Kantianism  in  our  post-­‐  Euclidean  and  post-­‐Newtonian  world?  (See   Wilson   2010.)   How   could   Kant’s   philosophy   ever   illuminate   the   nature   of   contemporary   physics   without   mentioning  biology  or  cognitive  sciences?  The  ideas  of  apodeictic  certainty  and  necessity,  which  formed  the   bedrock  of  Kant’s  program,  were  long  ago  discarded.   Yet  there  is  some  profound  insight  in  the  Kantian  tradition  that  con-­‐  temporary  HPS  can  still  draw  on.   And   this   is   the   idea   that   the   problem   of   knowledge,   of   how   we   come   to   know   what   we   do,   should   be   addressed  by   looking  at  the  natural  sciences  and  at  the  specific  ways   in  which  knowledge  of  the  natural   world  is  gained  in  the  first  instance.  Two  centuries  after  Kant  in  the  Prolegomena  raised  the  question  “How  is   natural  science  possible?”  contemporary  HPS  scholars  find  themselves  asking  similar  questions.  How  is   it   possible   for   us   to   have   the   experience   of   nature   delivered   by   contemporary   science?   How   has   our   experience  of  nature  changed  over  time  and  across  scientific  revolutions,  with  the  advent  of,  say,  relativity   theory   and   quantum   mechanics?   Most   important   of   all,   in   our   post-­‐Kuhnian   world,   how   could   these   transitions   occur?   Following   the   well-­‐trodden   path   of   neo-­‐Kantianism   at   the   turn   of   the   last   century,   contemporary   HPS   scholars   can   pursue   these   questions   with   an   eye   both   towards   the   broader   epistemological  framework  within  which  they  arise  and  towards  history  of  science  and  history  of  philosophy   of  science.   HPS  inquiry,  then,  does  not  reduce  to  a  mere  investigation  into  the  methodology  of  science.  But  it   becomes  continuous  with  epistemology,  or  with  what  the  Marburg  School  called  Erkenntnistheorie,  while   also  fruitfully  drawing  on  the  rich  and  complex  details  of  scientific  history.  In  the  past  two  decades,  Michael   Friedman  (1992,  1999,  2001,  2010)  has  shed  new  light  on  the  importance  of  this  philosophical  tradition  for   contemporary   HPS,   and   beautifully   exemplified   (in   our   view)   a   possible   way   in   which   HPS   can   avoid   the   aforementioned  disciplinary  enclaving.  “Dynamic  Kantianism,”  as  Friedman  brands  his  view,  shows  the  good   that  comes  from  embedding  the  practice  of  history  and  philosophy  of  science  within  epistemology  (broadly   construed).  And  it  has  opened  up  promising  new  avenues  of  research,  both  for  a  serious  re-­‐appraisal  of  the   historical  and  philosophical  foundations  of  physics  (see,  e.g.,  Ryckman  2005,  2012)  and  for  the  vast  area  that   goes  under  the  name  of  history  of  philosophy  of  science  (HOPOS),  whereby  the  history  of  the  discipline  can     provide  precious  insights  into  the  epistemological  foundations  of  HPS  (regardless  of  whether  one  embraces   dynamic  Kantianism;  see,  e.g.,  Richardson  1998,  2002).     How  to  Walk  the  Thin  Line  Between  Philosophy  and  Science:  The  “Back  to  Kant”  Recipe,  Again     But,   one   may   wonder,   how   can   Kantianism   help   with   the   challenge   of   naturalism   mentioned   above?   If   anything,  the  naturalistic  trend  in  the  philosophy  of  science  of  the  past  fifty  years  originated  as  a  reaction  to   Kantianism.  Quine’s  naturalism  was  the  last  straw  that  put  to  an  end  any  attempt    to  defend  not  only  Kant’s   distinction    between  analytic  and  synthetic  knowledge  but  also  Carnap’s  Aufbau   (rooted  as   it  was   in  the   Kantian   tradition;   see   Friedman   1999).   At   the   same   time,   Thomas   Kuhn’s   (1962)   new   agenda   for   HPS   cemented  what  Kitcher  (1992)  has  poignantly  portrayed  as  a  form  of  “radical  naturalism,”  which  was  bound   to   make   philosophy   of   science   a   chapter   of   history   of   science,   or,   after   Kuhn,   a   chapter   of   sociology   of   science  or  science  studies.  By  reacting  to  the  logical  empiricist  tradition  that  he  saw  still  exemplified  by  Carl   Gustav  Hempel,  Kuhn  rediscovered  the  central  role  that  history  of  science  plays  for  philosophical  questions   about  the  structure  of  scientific  revolutions  and  the  nature  of  theory-­‐choice.   The  healthy  naturalistic  trend  of  the  past  half  century  enjoins  philosophers  of  science  to  dig  into  the   details  of  actual  scientific  practice  as  much  as  it  enjoins  HPS  scholars  to  plunge  into  the  details  of  scientific   history.  We  witness  this  healthy  naturalistic  trend  in  the  BJPS  publishing  tradition,  where  first-­‐rate  work  in   contemporary  philosophy  of  science  comes  from  a  serious  engagement  with  scientific  practice.  New  exciting   research   on   neuroimaging   being   used   to   illuminate   old   philosophical   questions   about   theories   of   mind;   detailed   analyses   of   modelling   practices   bearing   on   pressing   questions   about   climate   change;   population   genetics  models  questioning  perennial  issues  about  the  nature  of  selection:  these  are  just  three  examples  of   how  contemporary  philosophy  of  science  has  flourished  under  the  naturalistic  trend.  In  the  HPS  tradition,   the  naturalistic  trend  is  in  turn  reflected  in  a  serious  engagement  with  the  sciences  of  the  past;  and  not  just   with   textual   evidence   but   also   with   past   experimental   traditions   and   the   conceptual   resources   made   available  by  them,  in  order  to  understand  what  images  of  nature  were  in  fact  accessible  to  the  scientists  of   the  past.   The  worry—as  always—is  how  to  walk  the  thin  line  that  separates  philosophy  from  science  (past  and   present).  Or  better,  how  to  draw  from  the  (past  and  present)  sciences  in  a  philosophically  compelling  way,   rather  than  leaving  the  sciences  to  speak  for  themselves,  as  it  were.  This  is  not  the  place  to  rehearse  the  old   dispute  whether  philosophy  (in  this  case,  philosophy  of  science)  should  or  should  not  have  a  normative  role.   Instead,  what  is  at  stake  is  the  nature  of  the  fruitful  interaction  between  science,  on  the  one  hand,  and  both   philosophy   of   science   and   HPS,   on   the   other   hand,   as   a   two-­‐way   (rather   than   one-­‐way)   street.   Scientific   practice  (past  or  present)  should  inform  philosophical  inquiry,  as  much  as  the  latter  can  and  should  throw   light  on  the  former  via  its  own  rules  and  investigative  methods.   The   “back   to   Kant”   recipe,   once   again,   may   help   here.   Kant’s   philosophy   of   natural   science   was   informed  by  the  sciences  of  his  time,  as  much  as  it  was  meant  to  illuminate  their  foundations  by  its  own   philosophical  lights.  Dynamic  Kantianism  no  longer  invokes  a  priori  categories  of  the  understanding  or  pure   forms  of  intuitions,  it  instead  takes  the  lead  from  logical  empiricism  (especially  Carnap  and  Reichenbach)  to   provide   a   new   spin   on   Kant’s   old   notion   of   “constitutive   a   priori,”   as   it   may   still   be   applicable   to   contemporary  physics  with  all  due  provisos  (see  Friedman  2001  and  2010).  Friedman’s  notion  of  “relativized   constitutive  a  priori”  is  at  the  centre  of  an  ongoing  debate,  as  many  HPS  scholars  would  firmly  resist  both  its   Kantian   spirit   and   its   applicability   to   modern   physics.   But   in   our   view,   the   merit   of   this   trend   consists   in   having  shed  new  light  on  the  role  of  our  scientific  history  both  for  philosophy  of  science  and,  more  broadly,   for  epistemology.  Within  this  tradition,  Newton  and  Einstein  become  philosophical  figures  in  their  own  right,     whose  scientific  work  integrates  into  and  illuminates  the  very  epistemological  foundations  of  science.  This  is   just  one  of  the  many  ways  (and  obviously  not  an  exclusive  one)  in  which  the  challenge  of  naturalism  can  be   satisfactorily  met.  It  certainly  does  so  with  an  eye  towards  philosophy,  more  in  general;  accordingly,  it  is  an   enticing  way  of  addressing  both  aforementioned  challenges.   If  the  aforementioned  interaction  between  philosophy  of  science,  epistemology,  and  history  of  science   constitutes   in   our   view   a   promising   frontier   in   the   field,   another   prominent   one   is   characterized   by   the   interaction  between  science,  philosophy  of  science,  and  metaphysics.  There  is  now  a  growing  appreciation   that  the  often  fraught  relationship  with  contemporary  metaphysics  might  be   improved,  to  the  benefit  of   both  metaphysicians  and  philosophers  of  science.  It  is  to  this  renewed  interest  in  the  metaphysics  of  science   that  we  turn  next.     Building  Bridges  Between  Metaphysics  and  Philosophy  of  Science     From  the  perspective  of  the  history  of  the  philosophy  of  science  over  the  past  one  hundred  years  or  so,  the   relationship  with  metaphysics  has  been  at  best  an  uneasy  one.  Dismissed  by  the  positivists  as  sterile  and   useless,  and  more  recently  as  a  dead  intellectual  pursuit,  metaphysics  has  been  further  excoriated  as  reliant   on  simplistic  intuitions  or,  at  best,  school  yard  science  (Ladyman  and  Ross  2007).  Nevertheless,  that  it  should   be   perceived   as   having   drifted   so   far   from   any   mooring   in   physics   is   surprising,   first,   given   the   way   its   heroes—here  the  likes  of  Putnam  and  Quine  in  particular  come  to  mind—drew  on  the  physics  of  the  day,   secondly,  given  the  way  in  which  today’s  practitioners  model  their  meta-­‐metaphysical  moves  on  what  they   see   as   the   methodology   of   the   sciences—appealing   to   simplicity,   explanatory   power,   and   the   like—and   thirdly,   and   perhaps   most   significantly,   given   the   widely   held   commitment   to   some   form   of   physicalism.   Perhaps  the  answer  lies  in  the  move  to  the  modal,  so  characteristic  of  modern  metaphysics,  as  a  result  of   which  the   latter   is  now  seen  as  primarily  concerned  with  the  possible,  rather  than  the  actual  (Callender,   2011).  Given  the  size  of  possibility  space  and  the  fact  that  actuality  occupies  such  a  small  fragment  of  it,  is  it   any  wonder—this  line  of  speculation  goes—that  metaphysicians  would  prefer  to  roam  the  vast  reaches  of   the  former  rather  than  get  to  grips  with  the  grubby  intricacies  of  the  latter?   Of   course,   if   the   limits   of   possibility   are   delineated   by   what   is   conceivable,   the   actual   may   appear   dwarfed   by   all   the   possibilities.   Conceivability   figures   prominently   in   philosophical   discussions   of   the   epistemology   of   modality   (for   a   useful   introduction   see   http://plato.stanford.edu/entries/modality-­‐ epistemology/).  Broadly  speaking,  success  in  conceiving  of  some  claim,  concept,  or,  indeed,  world  is  taken  to   support  (or  even  entail)  that  the  claim,  concept,  or  world  is  possible.  The  nature  of  conceiving,  whether  it  is   equivalent   to   imagining   or   goes   beyond   imagining,   the   extent   to   which   it   involves   construction   and   the   nature  of  such  construction  loom  large  in  these  discussions.  In  particular,  if  conceivability  is  strongly  tied  to   imaginability,  then  one  might  demand  general  conditions  governing  the  latter,  such  that  imagining  a  world   or  situation  is  sufficient  to  provide  evidence  for  the  possibility  of  such  a  situation.  In  the  absence  of  such   conditions,  one  should  at  least  acknowledge  that  conceivability  is  defeasible,  in  the  sense  that  one  may  not   be   aware   of   some   consideration   that   undermines   the   relevant   evidential   link   (Yablo   1993).   Black’s   two-­‐ sphere  counterexample  to  the  Identity  of  Indiscernibles  appears  to  fit  this  model  quite  nicely,  as  Hacking   (1975)  effectively  drew  on  considerations  from  physics  (specifically  General  Relativity)  to  show  that   what   Black  had  conceived  was  not  sufficiently  fine-­‐grained  to  serve  as  a  relevant  possibility.   Of  course,  even   if  no  such  consideration   is   immediately  apparent,   it  may  still  be  “out  there,”  as   it   were,  and  hence  one  might   insist  that  all  but  the  most  simple  conceptions  should  be  held  as  potentially   defeasible.   One   can   even   imagine,   or   conceive   of   (!),   a   kind   of   spectrum,   beginning   with   prima   facie   conceivability,   in  which  one  simply  conceives  of  or  imagines  a  situation  without  thinking  further  about  it,     moving  into  better  thought  out  conceivability,  in  which  the  relevant  situation  becomes  more  fine-­‐  grained,   and,  perhaps,  the  evidential  connection  decreases   in  defeasibility,  until  one  comes  to  some  form  of  fully   constrained   conceivability,   where   no   further   fine-­‐graining   is   possible,   and   the   link   to   possibility   is   indefeasible  because  the  possible  world  is  constrained  by  the  relevant  physics.   Many,   perhaps   most,   metaphysicians   are   still   hanging   out   at   the   far   end   of   the   spectrum,   where   conceivability  is,  if  not  unconstrained,  then  limited  only  by  intuition  or  broad  metaphysical  principles.  But   attitudes  appear  to  be  shifting.  In  recent  years  there  have  been  a  number  of  conferences  and  workshops   bringing  together  philosophers  of  science,  scientists,  and  metaphysicians  and  resulting  in  associated  special   issues  and  collections.  More  metaphysicians  are  beginning  to  engage  seriously  with  physics,  whether  via  a   consideration  of  the  implications  of  relativity  theory  for  issues  of  persistence  or  via  the  incorporation  of  non-­‐ supervenient   quantum   relations   in   bundle   theoretic   accounts   of   objects.   Here,   then,   there   are   welcome   signs  of  new  bridges  being  built  as  well  as  old  connections  being  used  in  new  ways.   But  more  than  this,  there  is  growing  awareness  that  in  their  exploration  of  the  space  of  possibilities   metaphysicians  have  developed  various  sets  of  tools  that  might  then  be  appropriated  and  usefully  employed   by  philosophers  of  science  (French  and  McKenzie  2012).  These  include  not  only  comparatively  well-­‐known   concepts  such  as  supervenience  and  dependence  but  also  general  strategies,  manoeuvres,  or  metaphysical   moves  in  general.  Thus,  Teller   long  ago  appropriated  the  concept  of  supervenience  for  the  philosophy  of   science   and   employed   it   to   articulate   a   view   of   quantum   entanglement   as   involving   non-­‐supervenient   relations  (Teller  1986).  Notions  of  dependence  of  course  feature  prominently  in  discussion  of  causation  but   have  recently  been  applied  to  consideration  of  the  relationship  between  numbers,  say,  and  mathematical   structures   (Linnebo   2008)   or   between   elementary   particles   and   the   symmetries   of   the   Standard   Model   (McKenzie  forthcoming).  Moving  to  the  more  general  level  of  argumentative  strategies  and  manoeuvres,  it  is   interesting   to   consider   how   eliminativism   in   physics,   for   example,   might   be   supported   by   the   moves   deployed  by  metaphysical  monists  and  nihilists  elsewhere.  Thus  Horgan  and  Potrč  (2008)  have  defended  a   monistic   ontology—there   is   only   one   thing,   called   (with   tongue   in   cheek)   “the   blob”—by   invoking   a   distinction  between  truth  as  direct  and  as  indirect  correspondence,  with  the  latter  articulated  in  terms  of   contextually  understood  semantic  standards.  Cameron  (2008),  on  the  other  hand,  offers  an  alternative  form   of   truth-­‐maker   theory,   in   which   the   truth   of   sentences   referring   to   putative   entities   is   grounded   in   something  other  than  those  entities.   So,   to   take   a   well-­‐known   example   from   the   history   of   science,   the   truth   of   statements   made   by   Eddington   about   his   table   can,   on   Cameron’s   account,   be   grounded   in   the   relevant   elementary   particles   “arranged   table-­‐wise.”   Now   the   sense   in   which   such   particles   can   be   regarded   as   the   metaphysicians’   infamous   “simples,”   and   also   the   sense   in   which   we   are   supposed   to   understand   “arrangement”   in   this   context,  remain  contentious,  and  here  there  is  a  need  for  further  to-­‐and-­‐fro  traffic  across  the  metaphysical   bridge.  But  the  point   is  that  there  are  potentially  useful  sets  of  tools   in  the  metaphysicians’  toolbox  that   philosophers  of  science  might  avail  themselves  of  and  deploy.  Of  course,  this  raises  further  issues,  such  as   how  tools  developed  far  away  in  possibility  space,  as  it  were,  can  be  of  any  use  in  understanding  science  as   developed   in   this,   the   actual,   world,   or   whether   the   use   of   such   tools   puts   the   philosophy   of   science   in   tension   with   the   naturalistic   tendency   that   is   currently   prominent.   If,   however,   we   accept   that   the   philosophy  of  science  has  to  achieve  an  appropriate  balance  between,  on  the  one  hand,  drawing  on  both  the   practice  and  the  history  of  science,  as  indicated  above,  and,  on  the  other  hand,  articulating  an  account  or   view  of  science  that  is  more  than  just  a  series  of  case  studies  and  that  involves  the  deployment  of  the  kinds   of  tools  just  outlined,  then  these  issues  cannot  be  avoided.         Conclusion     As  we  indicated,  this  is  a  very  personal  view  of  potentially  fruitful  developments  in  two  selected  areas  of   contemporary  philosophy  of  science.  As  well  as  exciting  new  work  in  the  philosophy  of  particular  sciences,   especially  philosophy  of  the  bio-­‐medical  sciences  and  neurosciences,  some  of  the  standard  topics  still  have   the   capacity   to   generate   interesting   lines   of   inquiry:   the   role   of   mathematics   in   science,   for   example,   particularly   its   role   in   explanation;   decision   theory   and   reasoning   under   uncertainty   in   general;   and   the   nature  of  scientific  representation,  where  useful  connections  have  been  drawn  with  the  philosophy  of  art,   just  to  name  a  few.  Even  the  realism-­‐antirealism  debate,  which  for  some  may  appear  stagnant  as  the  various   combatants  remain  locked  in  their  respective  positions,  shows  signs  of  renewed  vigour  as,  for  example,  the   role   of   case   studies   in   propping   up   such   positions   is   re-­‐examined.   Some   years   ago   an   elder   statesman   patiently  explained  to  one  of  us  that  the  philosophy  of  science  was  moribund  and  doomed  to  shrink  and  fade   as  its  original  impetus  lost  steam.  In  fact,  the  field  seems  more  alive  with  ideas  and  exciting  developments   than  ever,  as  it  engages  both  with  science  itself  and  with  philosophy  more  broadly.  As  editors,  we  are  proud   to  be  a  part  of  this  venerable  tradition  that  has  published,  and  will  continue  to  publish,  the  very  best  results   of  these  developments  in  the  pages  of  the  BJPS.     References     Arabatzis,   T.   2006.   Representing   Electrons:   A   Biographical   Approach   to
