According as the bonds uniting the peoples of the world together are multiplied and lightened by the progress of science and by unity of the doctrines and precepts that it deducts from facts, and imposes without violence and yet in a relentless manner to all convictions, these ideas have assumed a growing and more and more irresistible importance. They tend to become a purely human basis of nature, morality, and politics.
French chemist and politician (1827-1907)
Pierre Eugène Marcellin Berthelot FRS FRSE (25 October 1827 – 18 March 1907) was a French chemist and politician noted for the Thomsen-Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances, providing a large amount of counterevidence to the theory of Jöns Jakob Berzelius that organic compounds required organisms in their synthesis.

It not by reason of the egoistical satisfaction of our private vanity that the world-to-day pays homage to savants. No; it is because it knows that a savant really worthy of the name devotes a disinterested life to the great work of our epoch—I mean to say to the improvement, too slow, alas! for our taste, of the condition of every one, from the richest and happiest to the humble, the poor, and the suffering. That is what the public declared nine years ago in this same hall when honouring Pasteur. That is what my friend Chaplain has tried to express on the beautiful medal which the President of the Republic will presently offer me. I do not know if I have completely fulfilled noble ideal traced by the artist, but I have tried to make it object and end, the directing idea of my existence.

In effect, it may be declared emphatically that no one has a right to claim the exclusive merit of the brilliant discoveries of the past century. Science is essentially a collective work, prosecuted during the course of time by the efforts of a multitude of workers of every age and every nation, succeeding each other and associated in virtue of a tacit understanding for the research of truth in its purity, and for the application of this truth to the continual transformation of the condition of all men.

Gentlemen, since the first half of the century that has terminated, without going further back, the world has strangely altered. The men of my generation have seen come into play, beside and above the nature known since antiquity, if not an antithesis, a counter-nature... but a superior nature, and to some extent transcendent, where the power of indıvidual is centupled by the transformation of forces until then unknown or not understood, borrowed from light, magnetism, and electricity.

Chemistry is not a primitive science, like geometry or astronomy; it is constructed from the debris of a previous scientific formation; a formation half chimerical and half positive, itself founded on the treasure slowly amassed by the practical discoveries of metallurgy, medicine, industry, and domestic economy. It has to do with alchemy, which pretended to enrich its adepts by teaching them to manufacture gold and silver, to shield them from diseases by the preparation of the , and finally to obtain for them perfect felicity by identifying them with the soul of the world and the universal spirit.
There abides in nature a certain form of matter which, being discovered and brought by art to perfection, converts to itself, proportionally, all imperfect bodies that it touches. ...It rested on the indisputable appearance of an indefinite cycle of transformations, reproducing themselves in chemical operations, without either beginning or end.
