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

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

    What about a computer?

      If I understand your question correctly, and correct me if I am wrong, you are asking, (to paraphrase):

      But hang on, computers ‘think’ with electrical pulses (a series of 0s and 1s). They are not irrational for all that.

      But Lewis’s point is that if the human mind is a result of non-rational factors (atoms in motion) then we have no reason to trust the reasoning power of those ‘thoughts’ (since they are no more than atoms in motion, however complicated)

      If we arose from the impersonal slime, as it were, why should we give much weight to our powers of reasoning? Isn’t this just a kind of anthropocentric pride?

    Yeah I’m saying a computer is perfectly logical. Everything in it is cause and effect. It takes information in and it spits information out. And we value these calculations and give “weight” to them; they are in our lives everywhere from cars to washing machines to jets. Why couldn’t out brains be the same. Takes information in, plays with it, has a reaction.

  3. Zachariah Says:

    As for giving it weight, we don’t give our minds preemptive weight, we test and test and test again everything. And what we do give weight we give weight because of past experience.
