“A man of my spiritual intensity does not eat corpses.”

Doing what needs to be done may not make you happy, but it will make you great.

Those who cannot change their minds cannot change anything.

He who can, does. He who cannot, teaches.

You imagine what you desire, you will what you imagine and at last you create what you will.

To be in hell is to drift; to be in heaven is to steer.

I often quote myself. It adds spice to my conversation.

Both optimists and pessimists contribute to society. The optimist invents the aeroplane, the pessimist the parachute.

Do not waste your time on Social Questions. What is the matter with the poor is Poverty what is the matter with the rich is Uselessness.

Better keep yourself clean and bright; you are the window through which you must see the world.

There is no love sincerer than the love of food.

I have my own soul. My own spark of divine fire.

Beware of false knowledge; it is more dangerous than ignorance.

Life isn’t about finding yourself. Life is about creating yourself.

History is a people’s memory, and without a memory, man is demoted to the lower animals.

We don’t let animals suffer, so why humans?

Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it.

Humans are social animals. We seek belonging. We feel safer in a tribe than alone. But not all tribes are healthy.

Man is the only animal that blushes. Or needs to.

Man is the cruelest animal.
