Every society has a tendency to reduce it's opponents to caricatures.

We are unknown to ourselves, we men of knowledge - and with good reason. We have never sought ourselves - how could it happen that we should ever find ourselves? It has rightly been said: "Where your treasure is, there will your heart be also"; our treasure is where the beehives of our knowledge are.

There will always be rocks in the road ahead of us. They will be stumbling blocks or stepping stones; it all depends on how you use them.

With one more talent one frequently stands with greater instability than with one less, as a table stands better on three legs than on four.

Men seldom persevere in a vocation unless they believe or can convince themselves that it is fundamentally more important than anyother calling. Women are the same with their lovers.

Love your enemies because they bring out the best in you.

For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!
