As such, I also bear witness to the unexpected extent to which man is capable of defying and braving even the worst conditions conceivable.

Being tolerant does not mean that I share another one's belief. But it does mean that I acknowledge another one's right to believe, and obey, his own conscience.

Man's last freedom is his freedom to choose how he will react in any given situation

What man actually needs is not a tensionless state but rather the striving and struggling for some goal worthy of him. What he needs is not the discharge of tension at any cost, but the call of a potential meaning waiting to be fulfilled by him.

What will it matter to him if he notices that he is growing old? Has he any reason to envy the young people whom he sees, or wax nostalgic over his own lost youth? What reasons has he to envy a young person? For the possibilities that a young person has, the future which is in store for him? "No, thank you," he will think. "Instead of possibilities, I have realities in my past, not only the reality of work done and love loved, but of sufferings bravely suffered. These sufferings are even the things of which I am most proud, though these things are things that cannot inspire envy."

Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them. In other words, man is ultimately self-determining. Man does not simply exist but always decides what his existence will be, what he will become in the next moment.

It is the pursuit of happiness that thwarts happiness.
