“There certainly are changes of fashion in philosophy. When a new kind is in vogue, many things in the philosophy of an earlier day, which are of permanent value and perhaps highly relevant to contemporary problems, tend to be altogether forgotten or carelessly and ignorantly dismissed, simply because they occur in an out-of-date setting and are clad in an unfashionable dress. It is now quite certain that much of permanent value in Scholastic philosophy was ignored or contemned from this cause by Locke, Berkeley, Hume, and their followers. I have little doubt that the same is true mutatis mutandis of the attitude of many present-day philosophers towards the systems of monistic idealism which were fashionable at the beginning of this century. It is consoling to a philosopher's vanity not to pry too closely into the history of his subject, for otherwise he is liable to find that his discoveries have been anticipated and his fallacies refuted in advance by predecessors whom he has ignored or despised.”

Context: Philosophy is the science of estimating values. The superiority of any state or substance over another is determined by philosophy. By assigning a position of primary importance to what remains when all that is secondary has been removed, philosophy thus becomes the true index of priority or emphasis in the realm of speculative thought.

Two scientific activities are equally valid if they achieve results that are true. Now, how do you decide which activity is more valuable? The question of value is the basic question that the scientific administrator asks so that decisions can be made about funding priorities.

Query 28 : Are not all Hypotheses erroneous in which Light is supposed to consist of Pression or Motion propagated through a fluid medium?
Opticks (1704)
Context: To make way for the regular and lasting Motions of the Planets and Comets, it's necessary to empty the Heavens of all Matter, except perhaps some very thin Vapours, Steams or Effluvia, arising from the Atmospheres of the Earth, Planets and Comets, and from such an exceedingly rare Æthereal Medium … A dense Fluid can be of no use for explaining the Phænomena of Nature, the Motions of the Planets and Comets being better explain'd without it. It serves only to disturb and retard the Motions of those great Bodies, and make the frame of Nature languish: And in the Pores of Bodies, it serves only to stop the vibrating Motions of their Parts, wherein their Heat and Activity consists. And as it is of no use, and hinders the Operations of Nature, and makes her languish, so there is no evidence for its Existence, and therefore it ought to be rejected. And if it be rejected, the Hypotheses that Light consists in Pression or Motion propagated through such a Medium, are rejected with it.
And for rejecting such a Medium, we have the authority of those the oldest and most celebrated philosophers of ancient Greece and Phoenicia, who made a vacuum and atoms and the gravity of atoms the first principles of their philosophy, tacitly attributing Gravity to some other Cause than dense Matter. Later Philosophers banish the Consideration of such a Cause out of natural Philosophy, feigning Hypotheses for explaining all things mechanically, and referring other Causes to Metaphysicks: Whereas the main Business of natural Philosophy is to argue from Phenomena without feigning Hypotheses, and to deduce Causes from Effects, till we come to the very first Cause, which certainly is not mechanical.
