Quotes from the same author

Mother, recently I have discovered the one way in which human beings differ completely from other animals. Man has, I know, language, knowledge, principles, and social order, but don't all the other animals have them too, granted the difference of degree? Perhaps the animals even have religions. Man boasts of being the lord of all creation, but it would seem as if essentially he does not differ in the least from other animals. But, Mother, there was one way I thought of. Perhaps you won't understand. It's a faculty absolutely unique to man - having secrets. Can you see what I mean?

I must go on living. And, though it may be childish of me, I can't go on in simple compliance. From now on I must struggle with the world. I thought that Mother might well be the last of those who can end their lives beautifully and sadly, struggling with no one, neither hating nor betraying anyone. In the world to come there will be no room for such people. The dying are beautiful, but to live, to survive – those things somehow seem hideous and contaminated with blood.

I have always shook with fright before human beings. Unable as I was to feel the least particle of confidence in my ability to speak and act like a human being, I kept my solitary agonies locked in my breast. I kept my melancholy and my agitation hidden, careful lest any trace should be left exposed. I feigned an innocent optimism; I gradually perfected myself in the role of the farcical eccentric.

For someone like myself in whom the ability to trust others is so cracked and broken that I am wretchedly timid and am forever trying to read the expression on people's faces.
 Osamu Dazai
But happiness is being able to hope, however faintly, for happiness. So, at least, we must believe if we are to live in the world of today.
