Men are not willing to suffer the decision of things to be too easie, and therefore they mingle their own prejudices with truths, and so create great… - Bernard Le Bovier de Fontenelle

The calculus is to mathematics no more than what experiment is to physics, and all the truths produced solely by the calculus can be treated as truths of experiment. The sciences must proceed to first causes, above all mathematics where one cannot assume, as in physics, principles that are unknown to us. For there is in mathematics, so to speak, only what we have placed there... If, however, mathematics always has some essential obscurity that one cannot dissipate, it will lie, uniquely, I think, in the direction of the infinite; it is in that direction that mathematics touches on physics, on the innermost nature of bodies about which we know little.

At the time the book of Marquis de l'Hôpital had appeared, and almost all mathematicians began to turn to the new geometry of the infinite [that is, the new infinitesimal calculus], until then little known. The surprising universality of the methods, the elegant brevity of the proofs, the neatness and speed of the most difficult solutions, a singular and unexpected novelty, all attracted the mind and there was in the mathematical world a well marked revolution [une révolution bien marquée.

[A]bout the time of Alexander the Great, a little before Pyrrhus's days, there appear'd in Greece certain great Sects of Philosophers, such as the Peripateticks and Epicureans, who made a mock of Oracles. The Epicureans especially made sport with the paltry Poetry that came from Delphos. For the Priests hammered out their Verses as well as they could, and they often times committed faults against the common Rules of Prosodia. Now those Fleering Philosophers were mightily concerned that Apollo, the very God of Poetry, should come so far behind Homer, who was but a meer mortal, and was beholding to the same Apollo for his inspirations.
