Antoine Lavoisier

“Languages are true analytical methods.”

“We ought, in every instance, to submit our reasoning to the test of experiment, and never to search for truth but by the natural road of experiment and observation.”

“Nothing is lost, nothing is created, everything is transformed.”

“It is impossible to disassociate language from science or science from language.”

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

“The whole art of making experiments in chemistry is founded on the principle: we must always suppose an exact equality or equation between the principles of the body examined and those of the products of its analysis.”
