To mix science up with philosophy is only to produce a philosophy that has lost all its ideal value and a science that has lost all its practical value. It is for my private physician to tell me whether this or that food will kill me. It is for my private philosopher to tell me whether I ought to be killed.
I have seen a thousand graves opened, and always perceived that whatever was gone, the teeth and hair remained of those who had died with them. Is not this odd? They go the very first things in youth and yet last the longest in the dust.

A distinguished man should be as particular about his last words as he is about his last breath. He should write them out on a slip of paper and take the judgment of his friends on them.

When death comes, it's just like winter. We don't say, "There ought not to be winter."

No winter, no summer. No cold, no heat.
