Christopher Hitchens

The advice I've been giving to people all my life - that you may not be interested in the dialectic but the dialectic is interested in you; you can't give up politics, it won't give you up - was the advice I should have been taking myself.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
