Louis Pasteur

I am not afraid of the ruins, but of the new constructions.

My greatest strength is my tenacity.

I find that I am more and more interested in the infinitely small.

The true character of a man is not seen in the light, but in the dark.

The greatest discovery of all is to know that we are ignorant.

Life is a struggle, and I am a fighter.

I am a man of science, and I believe in facts.

One does not discover new lands without consenting to lose sight of the shore for a very long time.

The scientist has a duty to be skeptical.

My life is a series of experiments.

There are no small sciences, only small scientists.

I have no time for small talk, I am too busy with great discoveries.

The laboratory is my temple.

To be a scientist, you must be a dreamer.

I am a man of faith, but my faith is in science.

The greatest joy in life is to discover something new.

Don't be afraid to make mistakes, for in them lies the path to discovery.

The world is full of wonders, if only we take the time to look.

My only regret is that I have but one life to give to science.

The best way to predict the future is to create it.
