Superstition is the poetry of life.

One ought, every day at least, to hear a little song, read a good poem, see a fine picture, and, if it were possible, to speak a few reasonable words.

It is in self-limitation that a master first shows himself.

All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, till they take root in our personal experience.

Only people unable to produce anything themselves feel there is nothing there.

Science arose from poetry... when times change the two can meet again on a higher level as friends.
