It has been a privilege to pursue knowledge for its own sake and to see how it might help mankind in more practical ways.

Scientific discovery and scientific knowledge have been achieved only by those who have gone in pursuit of it without any practical purpose whatsoever in view.

Compassion is a practically acquired knowledge like dancing. You must do it and practice diligently day by day.

I think it's realistic to have hope. One can be a perverse idealist and say the easiest thing: 'I despair. The world's no good.' That's a perverse idealist. It's practical to hope because the hope is for us to survive as a human species. That's very realistic.

I do believe that most men live lives of quiet desperation. For despair optimism is the only practical solution. Hope is practical. Because eliminate that and it's pretty scary. Hope at least gives you the option of living.

I have often said that I wish I had invented blue jeans: the most spectacular the most practical the most relaxed and nonchalant. They have expression modesty sex appeal simplicity - all I hope for in my clothes.
