Like tourists huffing and puffing to reach the peak we forget the view on the way up.

Does not the discipline of the scientific spirit just commence when one no longer harbours any conviction?

Here the ways of men divide. If you wish to strive for peace of soul and happiness, then believe; if you wish to be a disciple of truth, then inquire.

You have not yet suffered enough! For you suffer only from yourselves, you have not yet suffered from man.

Human life is inexplicable, and still without meaning: a fool may decide its fate.
