Truth, whatever that is, definitely takes the hindmost

January 10, 2010

Boiled down to essentials, a nervous system enables the organism to succeed in the four F’s: feeding, fleeing, fighting, and reproducing. The principle chore of nervous systems is to get the body parts where they should be in order that the organism may survive…. . Improvements in sensorimotor control confer an evolutionary advantage: a fancier style of representing is advantageous so long as it is geared to the organism’s way of life and enhances the organism’s chances of survival. Truth, whatever that is, definitely takes the hindmost.

No thought is valid if it can be explained fully as the result of irrational causes

November 24, 2009

No thought is valid if it can be explained fully as the result of irrational causes…
A train of thought loses all rational credentials, as soon as it can be shown to be wholly the result of irrational causes.

C.S.Lewis, Miracles, p.27

If minds are wholly dependent on brains, and brains on biochemistry, and biochemistry (in the long run) on the meaningless flux of the atoms, I cannot understand how the thought of those minds should have any more significance than the sound of the wind in the trees

Naturalism undermines logic

September 8, 2009

Any argument we construct implies…laws (of logic)— the classical ones of identity, noncontradiction and the excluded middle. But that fact does not guarantee the ‘truthfulness’ of these laws in the sense that anything we think or say that obeys them necessarily relates to what is so in the objective, external universe. Moreover, any argument to check the validity of an argument is itself an argument that might be mistaken. When we begin to think like this, we are not far from an infinite regress; our argument chases its tail down the ever-receding corridors of the mind…Naturalism places us as human beings in a box. But for us to have any confidence that our knowing we are in a box is true, we need to stand outside the box or to have some other being outside the box provide us with information (theologians call this “revelation”). But there is nothing or no one outside the box to give us revelation, and we cannot ourselves transcend the box.
