We know the truth, 

not only by the reason, 

but also by the heart.

I cannot know what tomorrow will bring forth. 

I can know only what the truth is for me today. 

That is what I am called upon to serve, 

and I serve it in all lucidity.

that the most wickedest of men 

will do the most wickedest of things 

for the greatest good of everyone.

is not to get a man into heaven, 

but to get heaven into him.

Keep your face always toward the sunshine

 — and shadows will fall behind you.
