To his sister-in-law: What a contrast between us! You live a warm and glowing life, surrounded by loved ones whom you care for and who care for you; you are anchored in contentment. I drift about without rudder or compass, a wreck on the sea of life; I have no memories to cheer me, no pleasant illusions of the future to comfort me, or about me to satisfy my vanity. I have no family to furnish the only kind of survival that concerns us, no friends for the wholesome development of my affections, or enemies for my malice.

My home is where I work, and I work everywhere.

Contentment is the only real wealth.

Perhaps my dynamite plants will put an end to war sooner than your [pacifist] congresses. On the day two army corps can annihilate each other in one second all civilized nations will recoil from war in horror.

Justice is to be found only in the imagination.

A heart can no more be forced to love than a stomach can be forced to digest food by persuasion.

I regard large inherited wealth as a misfortune, which merely serves to dull men's faculties. A man who possesses great wealth should, therefore, allow only a small portion to descend to his relatives. Even if he has children, I consider it a mistake to hand over to them considerable sums of money beyond what is necessary for their education. To do so merely encourages laziness and impedes the healthy development of the individual's capacity to make an independent position for himself.
