38 Introduction
It should now be clear that in my view, there is much in what Peirce says here
that ought to remind us of Hegel.
Moreover, in a way that also resembles Hegel’s, Peirce believes that once we
do take up the task of reflecting on what our metaphysical position should be, we
will be led to endorse a form of conceptual realism, as no other view can avoid
falling victim to sceptical aporias. Peirce thus excoriates the implicit nominalistic
tendencies which he thinks have infected metaphysics,⁹⁰ as this has led us to feel
that thought is somehow cut off from reality,⁹¹ while also licensing a simple-
minded empiricist positivism, much in the way Hegel also feared;⁹² he also shares
with Hegel a sense that this nominalism will have an unfortunate impact on our
ethical and social thought.⁹³ In arguing for realism in this manner, Peirce will
influence of metaphysical errors, by paying no attention to metaphysics; but experience shows that
these men beyond all others are held in an iron vice of metaphysical theory, because by theories
that they have never called into question. No man is so enthralled by metaphysics as the totally
uneducated; no man is so free from its dominion as the metaphysician himself. Since, then, everyone
must have conceptions of things in general, it is most important that they should be carefully
constructed’.
⁹⁰ For an extended historical account by Peirce of the nominalism/realism debate (though his
conception of realism was to change somewhat in his later writings), see ‘Fraser’s The Works of
George Berkeley’, EP I, 83–105 (CP 8.7–38).
⁹¹ Cf. EP I, 100 (CP 8.30): ‘The nominalist, by isolating his reality so entirely from mental
influence as he has done, has made it something which the mind cannot conceive; he has created
the so often talked of ‘‘improportion between the mind and the thing in itself’’ ’; and EP I, 53
(CP 5.312): ‘The nominalist must admit that man is truly applicable to something; but he believes
that there is beneath this a thing in itself, an incognizable reality. His is the metaphysical figment’;
and EP II, 223: ‘[The nominalistic reasoner] would persuade us that the mind, that is to say our
opinions,—are filled with notions wholly unlike anything in the real world’.
⁹² Cf. EP I, 104 (CP 8.38): ‘The realistic philosophy of the last century has now lost all
its popularity, except with the most conservative minds. And science as well as philosophy
is nominalistic. The doctrine of the correlation of forces, the discoveries of Helmholtz, the
hypotheses of Liebig and Darwin, have all that character of explaining familiar phenomena
apparently of a peculiar kind by extending the operation of simple mechanical principles, which
belongs to nominalism. Or if the nominalistic character of these doctrines cannot be detected,
it will at least be admitted that they are observed to carry along with them those daughters of
nominalism,—sensationalism, phenomenalism, individualism, and materialism ....On the other
hand, it is allowable to suppose that science has no essential affinity with the philosophical views
with which it seems every year more associated. History cannot be held to exclude this supposition;
and science as it exists is certainly much less nominalistic than the nominalists think it should be.
Whewell represents it quite as well as Mill’. Cf. also CP 7.485: ‘But let me say a word here about
the attempt of Ernst Mach to show that all motion, even rotation, is merely relative. Mach belongs
to that school of soi disant experiential philosophers whose aim is to emancipate themselves from all
metaphysics and go straight to the facts. This attempt would be highly laudable,—were it possible
to carry it out. But experience shows that the experientialists are just as metaphysical as any other
philosophers, with this difference, however, that their pre-conceived ideas not being recognized by
them as such, are much more insidious and much more apt to fly in the face of all the facts of
observation’.
⁹³ Cf. EP I, 105 (CP 8.38): ‘But though the question of realism and nominalism has its roots
in the technicalities of logic, its branches reach about our life. The question whether the genus
homo has any existence except as individuals, is the question whether there is anything of any more
dignity, worth, and importance than individual happiness, individual aspirations, and individual
life. Whether men really have anything in common, so that the community is to be considered as an
