The present letter is a very long one, simply because I had no leisure to make it shorter.

Look somewhere else for someone who can follow you in your researches about numbers. For my part, I confess that they are far beyond me, and I am competent only to admire them.

Just as I do not know where I came from, so I do not know where I am going. All I know is that when I leave this world I shall fall forever into oblivion, or into the hands of an angry God, without knowing which of the two will be my lot for eternity. Such is my state of mind, full of weakness and uncertainty. The only conclusion I can draw from all this is that I must pass my days without a thought of trying to find out what is going to happen to me.

The sole cause of all human misery is the inability of people to sit quietly in their rooms.

Those are weaklings who know the truth and uphold it as long as it suits their purpose, and then abandon it.

The property of power is to protect.

If you do not love too much, you do not love enough.
