“Profound insights arise only in debate, with a possibility of counterargument, only when there is a possibility of expressing not only correct ideas but also dubious ideas.”

Open, honest and unabashed debate

I rather enjoy it when someone proposes their dubious ideas. It gives me something and someone to ridicule. In fact I consider it a duty of a sensible citizen to ridicule foolish ideas.

A necessary process for getting to the truth.

Profound insights arise in all kinds of places. Debate is good but it is not where the insights actually happen. It is just where they are tested.
