Philosophy is oddly in-between. On the one hand, it is supposed to deal with eternal verities and perpetual and necessary truths. So it ought to belong with mathematics and logic or biology. On the other hand, there are so many varieties of opposing philosophical positions (Platonic realism vs nominalism, physical realism vs idealism, and so on), and many more possibly combinations of such positions, that philosophy appears almost as subjective as poetry or painting. C.S. Peirce below gives a persuasive argument that nominalism is essentially English.
From very early times, it has been the chief intellectual characteristic of the
English to wish to effect everything by the plainest and directest means,
without unnecessary contrivance. In war, for example, they rely more than any
other people in Europe upon sheer hardihood, and rather despise military
science. The main peculiarities of their system of law arise from the fact that
every evil has been rectified as it became intolerable, without any
thoroughgoing measure. The bill for legalizing marriage with a deceased wife's
sister is yearly pressed because it supplies a remedy for an inconvenience
actually felt; but nobody has proposed a bill to legalize marriage with a
deceased husband's brother. In philosophy, this national tendency appears as a
strong preference for the simplest theories, and a resistance to any
complication of the theory as long as there is the least possibility that the
facts can be explained in the simpler way. And, accordingly, British
philosophers have always desired to weed out of philosophy all conceptions which
could not be made perfectly definite and easily intelligible, and have shown
strong nominalistic tendencies since the time of Edward I, or even earlier.
Berkeley is an admirable illustration of this national character, as well as of
that strange union of nominalism with Platonism, which has repeatedly appeared
in history, and has been such a stumbling-block to the historians of philosophy.
Peirce is discussing Berkeley here. I will turn to William of Ockham later, to whom a similar point applies. Can we say that Ockham is an essentially English philosopher? Who are the other English philosophers of whom we would say, as we say of Shakespeare or Chaucer or Milton, that they are represent Englishness, or English thinking, or English tendencies?
