If axioms and their implications have no contradictions, they pass my criterion of truth and existence [Hilbert]
|
|
Full Idea:
If the arbitrarily given axioms do not contradict each other with all their consequences, then they are true and the things defined by the axioms exist. For me this is the criterion of truth and existence.

From:
David Hilbert (Letter to Frege 29.12.1899 [1899]), quoted by R Kaplan / E Kaplan - The Art of the Infinite 2 'Mind'
|
|
A reaction:
If an axiom says something equivalent to 'fairies exist, but they are totally undetectable', this would seem to avoid contradiction with anything, and hence be true. Hilbert's idea sounds crazy to me. He developed full Formalism later.

A man cannot will to will, or will to will to will, so the idea of a voluntary will is absurd [Hobbes]
|
|
Full Idea:
The will is not voluntary: for a man can no more say he will will, than he will will will, and so make an infinite repetition of the word 'will', which is absurd and insignificant.

|
From:
Thomas Hobbes (Human Nature [1640], Ch.XII.5)
|
|
A reaction:
A nice simple point, allied to Nietzsche's notion that thoughts are uncontrollable (Idea 2291). Even Aquinas, who is quite a fan of free will, spotted the problem (Idea 1854). Personally I agree with Hobbes. Free will is a shibboleth.

Life has no end (not even happiness), because we have desires, which presuppose a further end [Hobbes]
|
|
Full Idea:
For an utmost end, in which the ancient philosophers have placed felicity, there is no such thing in this world, nor way to it: for while we live, we have desires, and desire presupposeth a further end.
|
|
From:
Thomas Hobbes (Human Nature [1640], Ch.VII.6)
|
|
A reaction:
Kant's definition of happiness (Idea 1452) seems to be the underlying idea, and hence with the same implication (of impossibility). However, an alcoholic locked in a brewery would seem to have all that Hobbes requires for happiness.

Lust involves pleasure, and also the sense of power in pleasing others [Hobbes]
|
|
Full Idea:
Lust consists of two appetites together, to please, and to be pleased, and the delight men take in delighting is not sensual, but a pleasure or joy of the mind consisting in the imagination of the power they have so much to please.
|
|
From:
Thomas Hobbes (Human Nature [1640], Ch.IX)
|
|
A reaction:
Hobbes would rather burst a blood-vessel than admit any altruism. If you take pleasure in pleasing someone else, why can't that simply be because of the other person's pleasure, with which we sympathise, rather than relishing our own 'power'?
