Science is sympathetic to truth as correspondence, since it depends on observation [Quine]
|
|
Full Idea:
Science, thanks to its links with observation, retains some title to a correspondence theory of truth.
|
|
From:
Willard Quine (On the Nature of Moral Values [1978], p.63)
|
|
A reaction:
I would describe what he is affirming as a 'robust' theory of truth. An interesting aside, given his usual allegiance to disquotational, and even redundancy, accounts of truth. You can hardly rely on observations if you think they contain no truth.

Leaves are unequal, but we form the concept 'leaf' by discarding their individual differences [Nietzsche]
|
|
Full Idea:
Every concept arises through the setting equal of the unequal. Just as it is certain that one leaf is never wholly equal to another, so it is certain that the concept leaf is formed by arbitrarily discarding these individual differences.

From:
Friedrich Nietzsche (On Truth and Lies in a Nonmoral Sense [1872]), quoted by John Richardson - Nietzsche's System 2.1.1 n28
|
|
A reaction:
Nietzsche adds an interesting aspect to psychological abstraction, of abstracting away the differences between things, which we might label as the (further) capacity for Equalisation. If two cars differ only in a blemish, we abstract away the blemish.

A machine is best defined by its final cause, which explains the roles of the parts [Leibniz]
|
|
Full Idea:
Any machine ...is best defined in terms of its final cause, so that in the description of the parts it is therefore apparent in what way each of them is coordinated with the others for the intended us.
|
|
From:
Gottfried Leibniz (The Human Body is a sort of Machine [1683], p.290), quoted by Richard T.W. Arthur - Leibniz 3 'Machines'
|
|
A reaction:
We would use the 'function', an inherently teleological concept, and a concept which is almost indispensable for giving an illuminating description of the world. If nature is dispositional, it points towards things. Leibniz views persons as machines.
