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.


The 9 ideas with the same theme [how incorrect judgements occur]:

I make errors because my will extends beyond my understanding [Descartes]
Most errors of judgement result from an inaccurate perception of the facts [Descartes]
People make calculation mistakes by misjudging the figures, not calculating them wrongly [Spinoza]
Do incorrect judgements have non-existent, or mental, or external objects? [Russell]
Surprise is a criterion of error [Russell]
To explain false belief we should take belief as relating to a proposition's parts, not to the whole thing [Russell]
The theory of error seems to need the existence of the non-existent [Russell]
In order to explain falsehood, a belief must involve several terms, not two [Russell]
The form of a proposition must show why nonsense is unjudgeable [Wittgenstein]
