As soon as questions of will or decision or reason or choice of action arise human science is at a loss.

Whence come I and whither go I? That is the great unfathomable question the same for every one of us. Science has no answer to it.

It seems to me that socialists today can preserve their position in academic economics merely by the pretense that the differences are entirely moral questions about which science cannot decide.

In questions of science the authority of a thousand is not worth the humble reasoning of a single individual.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

Science is wonderfully equipped to answer the question 'How?' but it gets terribly confused when you ask the question 'Why?'

It's a sad indication of where Washington has come where policy differences almost necessarily become questions of integrity. I came to Washington in the late '70s and people had the ability in the past to have intense policy differences but didn't feel the need to question the other person's character.

The question I love to get asked is: 'What's the hardest part of your job?' And literally the answer is probably real sad but it's to just to be me. Like it's really hard because I think people you know have a set idea of what a pop star should be.
