The Boundless cannot exist on its own, and must have something contrary to it [Aristotle on Anaximander]
|
|
Full Idea:
Those thinkers are in error who postulate ...a single matter, for this cannot exist without some 'perceptible contrariety': this Boundless, which they identify with the 'original real', must be either light or heavy, either hot or cold.

From:
comment on Anaximander (fragments/reports [c.570 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 329a10
|
|
A reaction:
A dubious objection, I would say. If there has to be a contrasting cold thing to any hot thing, what happens when the cold thing is removed?

Laws of nature have very little application in biology [Machamer/Darden/Craver]
|
|
Full Idea:
The traditional notion of a law of nature has few, if any, applications in neurobiology or molecular biology.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 3.2)
|
|
A reaction:
This is a simple and self-evident fact, and bad news for anyone who want to build their entire ontology around laws of nature. I take such a notion to be fairly empty, except as a convenient heuristic device.

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.
