Hippocrates Quotes
But the Quincunx of Heaven runs low, and 'tis time to close the five ports of knowledge. We are unwilling to spin out our awaking thoughts into the phantasmes of sleep, which often continueth præcogitations; making Cables of Cobwebbes and Wildernesses of handsome Groves. Beside Hippocrates hath spoke so little and the Oneirocriticall Masters, have left such frigid Interpretations from plants, that there is little encouragement to dream of Paradise it self. Nor will the sweetest delight of Gardens afford much comfort in sleep; wherein the dulnesse of that sense shakes hands with delectable odours; and though in the Bed of Cleopatra, can hardly with any delight raise up the ghost of a Rose.
Thomas Browne
But absolutely nothing remains of that one and only medicament of which Hippocrates makes mention (darkly and mystically, I admit) in several places, and still less are its operations understood, inasmuch as no one now searches with lynx-like eyes into the profound depths of true natural philosophy, to gain an accurate knowledge of its composition and its virtues.

From the time when Guldberg and Waage gave quantitative form to the speculations of the physicist Berthollet, a clear conception of chemical equilibrium, in sharp contrast to an anthropomorphic theory of affinity dating back to Hippocrates and Barchausen, has yielded rich and abundant fruit.

By the time of Hippocrates of Chios the scope of Greek geometry was no longer even limited to the Elements; certain special problems were also attacked which were beyond the power of the geometry of the straight line and circle, and which were destined to play a great part in determining the direction taken by Greek geometry in its highest flights. The main problems in question were three: (1) the doubling of the cube, (2) the trisection of any angle, (3) the squaring of the circle; and from the time of Hippocrates onwards the investigation of these problems proceeded pari passu with the completion of the body of the Elements.

The actual writers of Elements of whom we hear were the following. Leon, a little younger than Eudoxus, was the author of a collection of propositions more numerous and more serviceable than those collected by Hippocrates. Theudius of Magnesia, a contemporary of Menæchmus and Dinostratus, "put together the elements admirably, making many partial or limited propositions more general". Theudius's book was no doubt the geometrical text-book of the Academy and that used by Aristotle.

Hippocrates also attacked the problem of doubling the cube. ...Hippocrates did not, indeed, solve the problem, but he succeeded in reducing it to another, namely, the problem of finding two mean proportionals in continued proportion between two given straight lines, i. e. finding x, y such that a:x=x:y=y:b, where a, b are the two given straight lines. It is easy to see that, if a:x=x:y=y:b, then b/a = (x/a)3, and, as a particular case, if b=2a, x3=2a3, so that the side of the cube which is double of the cube of side a is found.

Hippocrates himself is an example of the concurrent study of the two departments. On the one hand, he was the first of the Greeks who is known to have compiled a book of Elements. This book, we may be sure, contained in particular the most important propositions about the circle included in Euclid, Book III. But a much more important proposition is attributed to Hippocrates; he is said to have been the first to prove that circles are to one another as the squares on their diameters (= Eucl. XII., 2) with the deduction that similar segments of circles are to one another as the squares on their bases. These propositions were used by him in his tract on the squaring of lunes, which was intended to lead up to the squaring of the circle. The latter problem is one which must have exercised practical geometers from time immemorial. Anaxagoras for instance is said to have worked at the problem while in prison.

Both Plato and Aristotle approved of abortion, the former in the interests of wise population policy, the latter chiefly on the ground that it was an element of the family's proper freedom in the state. Hippocrates' words on the subject are, in the original Greek, somewhat less blunt and categorical than modern takers of the Hippocratic Oath have sometimes suggested. All Hippocrates says is: "I will not give to a woman a pessary to produce abortion.” There were other means of abortion known to the Greeks, none of which Hippocrates abjures.
Hippocrates
As a guide to engineering ethics, I should like to commend to you a liberal adaptation of the injunction contained in the oath of Hippocrates that the professional man do nothing that will harm his client. Since engineering is a profession which affects the material basis of everyone's life, there is almost always an unconsulted third party involved in any contact between the engineer and those who employ him - and that is the country, the people as a whole. These, too, are the engineer's clients, albeit involuntarily. Engineering ethics ought therefore to safeguard their interests most carefully. Knowing more about the public effects his work will have, the engineer ought to consider himself an "officer of the court” and keep the general interest always in mind.
