I've been thinking Hobbes -- - On a weekend? - Well, it wasn't on purpose...

Few people think more than two or three times a year. I have made an international reputation for myself by thinking once or twice a week

Thinking is the most unhealthy thing in the world, and people die of it just as they die of any other disease. Fortunately, in England at any rate, thought is not catching. Our splendid physique as a people is entirely due to our national stupidity

Thinking is the hardest work there is, which is probably the reason why so few engage in it

As long as your going to be thinking anyway, think big

Thinking is the essence of wisdom

To live is to think

Truth cannot afford to be tolerant where it faces positive evil

You can't think and hit at the same time

Never speak more clearly than you think
