We may think that science uses a form of nominalism as we formulate theories whose simplifications name concepts used in the theory that may be useful for the theory, but not reflect the deep reality. An oft cited one is the use of species in Biology. Ernst Mayr argued against a simple "typological thinking," found in biology (even evolutionary biology). Belief in the reality of "species" as a general form is a type of Platonic idealism, but in practice its use in theory seems to be just a nominalist use.

Unfortunately, that point of view was fairly widespread among 20th century analytic philosophers. Some of them even claimed that all the laws of physics are merely verbal (or mathematical) summaries of observations. That view is true of some so-called laws, such as Bode's law, which states a simple numerical formula for the distance of the planets from the sun. Most physicists, however, are realists with regard to the laws of physics: they believe that there is something real underlying the laws that have been tested and verified under many kinds of conditions by large numbers of experimenters. The option of treating events as real and allowing quantified variables to range over events is usually called 'event semantics' and attributed to Donald Davidson. However, Peirce insisted that it was appropriate to quantify over events long before Davidson, and Whitehead made events the central focus of his ontology. Furthermore, Davidson had taken Whitehead's course when he was an undergraduate at Harvard. He was so enthusiastic about Whitehead's approach that he decided to study for a PhD in philosophy at Harvard. Unfortunately, Davidson was suckered into a "bait and switch" deal because Whitehead retired, and Davidson was stuck with Quine as his thesis advisor. Quine was a nominalist who had no sympathy with Whitehead's philosophy, so Davidson couldn't write his dissertation on event semantics under Quine. But Davidson did return to event semantics after he got tenure and didn't have to "suffer the slings and arrows" of the nominalists. But it would be more appropriate to call event semantics the Plato-Aristotle-Peirce-Whitehead-Davidson theory. And by the way, you could also add the logician Alonzo Church to the anti-Quine, anti-nominalist group. Church presented the following paper at Harvard, especially because he knew it would annoy Quine: http://www.jfsowa.com/ontology/church.htm Following is the title and opening paragraph of that paper. John _________________________________________________________________ The ontological status of women and abstract entities By Alonzo Church Goodman says somewhere that he finds abstract entities difficult to understand. And from a psychological viewpoint it is certainly his dislike and distrust of abstract entities which leads him to propose an ontology from which they are omitted. Now a misogynist is a man who finds women difficult to understand, and who in fact considers them objectionable incongruities in an otherwise matter-of-fact and hard-headed world. Suppose then that in analogy with nominalism the misogynist is led by his dislike and distrust of women to omit them from his ontology. Women are not real, he tells himself, and derives great comfort from the thought -- there are no such things. This doctrine let us call ontological misogyny...
