[how incorrect judgements occur]

9 ideas
I make errors because my will extends beyond my understanding [Descartes]
     Full Idea: My errors are owing simply to the fact that, since the will extends further than the intellect, I do not contain the will within the same boundaries, but extend it to things I do not understand.
     From: René Descartes (Meditations [1641], §4.58)
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.
People make calculation mistakes by misjudging the figures, not calculating them wrongly [Spinoza]
     Full Idea: When men make mistakes in calculation, they have one set of figures in their mind, and another on the paper. If we could see into their minds, they do not make a mistake.
     From: Baruch de Spinoza (The Ethics [1675], II Pr 47)
     A reaction: A wonderfully optimistic assertion of faith in reason! He seems to imply an infallibility in reason, which seems a bit implausible. If I make 7+6=14, MUST I have muddled the 6 with a 7? Presumably Spinoza was good at arithmetic.
Do incorrect judgements have non-existent, or mental, or external objects? [Russell]
     Full Idea: Correct judgements have a transcendent object; but with regard to incorrect judgements, it remains to examine whether 1) the object is immanent, 2) there is no object, or 3) the object is transcendent.
     From: Bertrand Russell (Meinong on Complexes and Assumptions [1904], p.67)
     A reaction: Why is it that only Russell seems to have taken this problem seriously? Its solution gives the clearest possible indicator of how the mind relates to the world.
Surprise is a criterion of error [Russell]
     Full Idea: Surprise is a criterion of error.
     From: Bertrand Russell (My Philosophical Development [1959], Ch.15)
     A reaction: Russell is not too precise about this, but it is a nice point. Surprise is thwarted expectation, which implies prior misjudgement.
To explain false belief we should take belief as relating to a proposition's parts, not to the whole thing [Russell]
     Full Idea: To explain belief in what is false we shall have to regard what is called belief in a proposition as not a thought related to the proposition, but rather as a thought related to the constituents of the proposition.
     From: Bertrand Russell (Papers of 1906 [1906], V.321), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 40 '1906'
     A reaction: Russell proposed a new theory of judgement, in order to explain erroneous judgements, given that true propositions are identical with facts. Of course there might be errors about the constituents, as well as about their structure. Othello is his example.
The theory of error seems to need the existence of the non-existent [Russell]
     Full Idea: It is very difficult to deal with the theory of error without assuming the existence of the non-existent.
     From: Bertrand Russell (The Philosophy of Logical Atomism [1918], §IV.3)
     A reaction: This problem really bothered Russell (and Plato). I suspect that it was a self-inflicted problem because at this point Russell had ceased to believe in propositions. If we accept propositions as intentional objects, they can be as silly as you like.
In order to explain falsehood, a belief must involve several terms, not two [Russell]
     Full Idea: The relation involved in judging or believing must, if falsehood is to be duly allowed for, be taken to be a relation between several terms, not between two.
     From: Bertrand Russell (Problems of Philosophy [1912], Ch.12)
     A reaction: His point is that if a belief relates to one object ('D's love for C') it will always be true. Russell is trying to explain what goes wrong when we believe a falsehood. It is not clear how the judgement 'x exists' involves several terms.
The form of a proposition must show why nonsense is unjudgeable [Wittgenstein]
     Full Idea: The correct explanation of the form of the proposition 'A judges p' must show that it is impossible to judge a nonsense. (Russell's theory does not satisfy this condition).
     From: Ludwig Wittgenstein (Tractatus Logico-Philosophicus [1921], 5.5422)
     A reaction: In Notebooks p.96 LW gives the example 'this table penholders the book'. I take it Russell wanted judgement to impose unified meaning on sentences, but LW shows that assembling meaning must precede judgement. LW is right.
