Antoine Lavoisier

The nomenclature of chemistry should be a true picture of the science, and should facilitate its study.

It is by the exactness of our experiments that we must judge the truth of our theories.

The most important thing in science is to be honest with ourselves about what we know and what we don't know.

The whole of chemistry is founded on the principle that the quantity of matter remains constant in all operations, and that nothing is created or destroyed, but everything is transformed.

We must simplify the language of chemistry, and make it more philosophical, so that it may be understood by all.

It is not enough to know, one must apply; it is not enough to wish, one must do.

I consider it one of the greatest misfortunes of my life that I did not have the opportunity to work with you more closely.

My dear friend, the progress of chemistry is so rapid that one must run to keep up with it.

The art of drawing conclusions from experiments and observations is the most important part of experimental philosophy.

I have tried to make chemistry a science of observation and measurement.

The more I reflect on the subject, the more I am convinced that the true elements are those which we cannot decompose.

My wife is an excellent assistant; she understands my work perfectly and often helps me with my experiments.

The revolution in chemistry is accomplished.

It is not enough to demonstrate a truth; one must also make it understood.

I have no other ambition than to serve my country and humanity.

The future of chemistry depends on the precision of our experiments and the clarity of our language.

I find great pleasure in the pursuit of knowledge, even when it leads to unexpected results.

The greatest discoveries are often made by those who dare to question established ideas.

My work on combustion has led me to believe that phlogiston does not exist.

The exactness of weights and measures is the foundation of all sound chemistry.
