We must trust to nothing but facts: These are presented to us by Nature, and cannot deceive.

Life is a chemical process.

Antoine Lavoisier

It required 85 parts by weight of oxygen and 15 parts of hydrogen to compose 100 parts of water.

Antoine Lavoisier

I consider nature a vast chemical laboratory in which all kinds of composition and decompositions are formed.

Antoine Lavoisier

Languages are true analytical methods.

Antoine Lavoisier

Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed.

Antoine Lavoisier

Vegetation is the basic instrument the creator uses to set all of nature in motion.

Antoine Lavoisier

Nothing is born, nothing dies.

Antoine Lavoisier

Antoine Lavoisier

In performing experiments, it is necessary… that they be simplified as much as possible, and that every circumstance that could complicate the results should be completely removed.

Antoine Lavoisier

In nature nothing is created, nothing is lost, everything changes.

Antoine Lavoisier

It took them only an instant to cut of that head, but it is unlikely that a hundred years will suffice to reproduce a singular one.
