Mathematicians do not study objects, but relations between objects [Poincaré]
|
|
Full Idea:
Mathematicians do not study objects, but relations between objects; it is a matter of indifference if the objects are replaced by others, provided the relations do not change. They are interested in form alone, not matter.

From:
Henri Poincaré (Science and Hypothesis [1902], p.20), quoted by E Reck / M Price - Structures and Structuralism in Phil of Maths §6
|
|
A reaction:
This connects modern structuralism with Aritotle's interest in the 'form' of things. Contrary to the views of the likes of Frege, it is hard to see that the number '7' has any properties at all, apart from its relations. A daffodil would do just as well.

When we need to do something, we depute an inner servant to remind us of it [Proust]
|
|
Full Idea:
Whenever we have something definite to do at a given moment, we depute a certain person inside us who is accustomed to that sort of duty to keep an eye on the clock and warn us of the time. This inner servant reminded me that Albertine was coming soon.

From:
Marcel Proust (Remembrance of Things Past [1922], Cities.2.1)
|
|
A reaction:
I think Proust is wrong that we 'depute' this servant. I think it comes as a built-in feature, and the servant could never be abandoned or sacked, no matter how poor the service. Each of us is a team, which includes servants.

The aim of science is just to create a comprehensive, elegant language to describe brute facts [Poincaré, by Harré]
|
|
Full Idea:
In Poincaré's view, we try to construct a language within which the brute facts of experience are expressed as comprehensively and as elegantly as possible. The job of science is the forging of a language precisely suited to that purpose.
|
|
From:
report of Henri Poincaré (The Value of Science [1906], Pt III) by Rom Harré - Laws of Nature 2
|
|
A reaction:
I'm often struck by how obscure and difficult our accounts of self-evident facts can be. Chairs are easy, and the metaphysics of chairs is hideous. Why is that? I'm a robust realist, but I like Poincaré's idea. He permits facts.
