Quote

If everything in chemistry is explained in a satisfactory manner without the help of phlogiston, it is by that reason alone infinitely probable that the principle does not exist that it is a hypothetical body, a gratuitous supposition indeed, it is in the principles of good logic, not to multiply bodies without necessity.

It is almost possible to predict one or two days in advance, within a rather broad range of probability, what the weather is going to be it is even thought that it will not be impossible to publish daily forecasts, which would be very useful to soci.

Thus, while I thought myself employed only in forming a Nomenclature, and while I proposed to myself nothing more than to improve the chemical language, my work transformed itself by degrees, without my being able to prevent it, into a treatise upon the Elements of Chemistry.

This theory [the oxygen theory] is not as I have heard it described, that of the French chemists, it is mine (elle est la mienne) it is a property which I claim from my contemporaries and from posterity.

Nothing is born, nothing dies.

Diminish the mass of evils that afflict the human species, increase enjoyment and well-being. And even if the new routes opened up could prolong the average life of mankind by only a few hours, or even a few days, then the scientist, too could aspire.

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

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 nourishing themselves,what they losethrough respiration, the lamp would very soon run out of oil and the animal would perish, just as the lamp goes out when it lacks fuel.
Antoine Lavoisier
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
Image
Languages are true analytical methods.

I am young and avid for glory.

Perhaps... some day the precision of the data will be brought so far that the mathematician will be able to calculate at his desk the outcome of any chemical combination, in the same way, so to speak, as he calculates the motions of celestial bodies.
Antoine Lavoisier
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 be completely removed.

Vegetables are organized bodies that grow on the dry areas of the globe and within its waters. Their function is to combine immediately the four elements and to serve as food for animals.

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

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

As ideas are preserved and communicated by means of words, it necessarily follows that we cannot improve the language of any science, without at the same time improving the science itself neither can we, on the other hand, improve a science without improving the language or nomenclature which belongs to it.

Experiments upon vegetation give reason to believe that light combines with certain parts of vegetables, and that the green of their leaves, and the various colors of flowers, is chiefly owing to this combination.
Antoine Lavoisier
Image
Mathematicians come to the solution of a problem by the simple arrangement of the data, and reducing the reasoning to such simple operations, to judgments so brief, that they never lose sight of the evidence that serves as their guide.
Antoine Lavoisier

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 commonly thought to be. . . .
