The art of drawing conclusions from experiments and observations consists in evaluating probabilities and in estimating whether they are sufficiently great or numerous enough to constitute proofs. This kind of calculation is more complicated and more difficult than it is… — Antoine Lavoisier Copy Share Image
Imagination, on the contrary, which is ever wandering beyond the bounds of truth, joined to self-love and that self-confidence we are so apt to indulge, prompt us to draw conclusions which are not immediately derived from facts. — Antoine Lavoisier Copy Share Image
The impossibility of separating the nomenclature of a science from the science itself, is owing to this, that every branch of physical science must consist of three things; the series of facts which are the objects of the science, the ideas which represent these facts, and the words by which these ideas are expressed. Like three impressions of the same… — Antoine Lavoisier Copy Share
I consider nature a vast chemical laboratory in which all kinds of composition and decompositions are formed. — Antoine Lavoisier Copy Share Image
Perhaps... some day the precision of the data will be brought so far that the mathematician will be able to calculate at his desk… — Antoine Lavoisier Copy Share Image
Experiments upon vegetation give reason to believe that light combines with certain parts of vegetables, and that the green of their leaves, and the… — Antoine Lavoisier Copy Share Image
“About eight days ago I discovered that sulfur in burning, far from losing weight, on the contrary, gains it; it is the same with… — Antoine Lavoisier Copy Share Image
It required 85 parts by weight of oxygen and 15 parts of hydrogen to compose 100 parts of water. — Antoine Lavoisier Copy Share Image
It is impossible to disassociate language from science...To call forth a concept, a word is needed. — Antoine Lavoisier Copy Share Image
Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of… — Antoine Lavoisier Copy Share Image
Since it is the very substance of the animal, it is the blood which transports the fuel.If the animal did not habitually replace, through… — Antoine Lavoisier Copy Share Image
If everything in chemistry is explained in a satisfactory manner without the help of phlogiston, it is by that reason alone infinitely probable that… — Antoine Lavoisier Copy Share Image
In performing experiments, it is necessary... that they be simplified as much as possible, and that every circumstance that could complicate the results should… — Antoine Lavoisier Copy Share Image
