At every crossroads on the path that leads to the future, tradition has placed 10,000 men to guard the past.

I have never for one instant seen clearly within myself. How then would you have me judge the deeds of others?

The decent moderation of today will be the least of human things tomorrow. At the time of the Spanish Inquisition, the opinion of good sense and of the good medium was certainly that people ought not to burn too large a number of heretics; extreme and unreasonable opinion obviously demanded that they should burn none at all.

If you love yourself meanly, childishly, timidly, even so shall you love your neighbor.

At every crossroad on the way that leads to the future, each progressive spirit is opposed by a thousand men appointed to guard the past.

I have done what I could do in life, and if I could not do better, I did not deserve it. In vain I have tried to step beyond what bound me.

It is death that is the guide of our life, and our life has no goal but death.
