Joseph-Louis Lagrange

The important thing is not to stop questioning. Curiosity has its own reason for existence.

Anyone who has never made a mistake has never tried anything new.

Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.

The only source of knowledge is experience.

Logic will get you from A to B. Imagination will take you everywhere.

The value of a man should be seen in what he gives and not in what he is able to receive.

Try not to become a man of success, but rather try to become a man of value.

The difference between genius and stupidity is that genius has its limits.

Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.

It is a miracle that curiosity survives formal education.

The only thing that interferes with my learning is my education.

I never think of the future – it comes soon enough.

The hardest thing in the world to understand is the income tax.

Reality is merely an illusion, albeit a very persistent one.

Science without religion is lame, religion without science is blind.

The most incomprehensible thing about the world is that it is comprehensible.

Joy in looking and comprehending is nature's most beautiful gift.

The only real valuable thing is intuition.

I believe in intuitions and inspirations. I sometimes feel that I am right. I do not know that I am.

The only way to escape the corruptible effect of praise is to go on working.
