18265 | We don't judge by combining subject and concept; we get a concept by splitting up a judgement [Frege] |
Full Idea: Instead of putting a judgement together out of an individual as subject and an already previously formed concept as predicate, we do the opposite and arrive at a concept by splitting up the content of possible judgement. | |
From: Gottlob Frege (Boole calculus and the Concept script [1881], p.17) | |
A reaction: This is behind holistic views of sentences, and hence of whole languages, and behind Quine's rejection of 'properties' inferred from the predicates in judgements. |
5007 | Most errors of judgement result from an inaccurate perception of the facts [Descartes] |
Full Idea: What usually misleads us is that we very frequently form a judgement although we do not have an accurate perception of what we judge. | |
From: René Descartes (Principles of Philosophy [1646], I.33) | |
A reaction: This seems to me a generally accurate observation, particularly in the making of moral judgements (which was probably not what Descartes was considering). The implication is that judgements are to a large extent forced by our perceptions. |
