He who thinks half-heartedly will not believe in God; but he who really thinks has to believe in God. - Isaac Newton

No great discovery was ever made without a bold guess.

For though some stop was put to the Cataphrygian Christianity, by Provincial Councils, till the fourth century; yet the Roman Emperors then turning Christians, and great multitudes of heathens coming over in outward profession, these found the Cataphrygian Christianity more suitable to their old principles, of placing religion in outward forms and ceremonies, holy-days, and doctrines of Ghosts, than the religion of the sincere Christians: wherefore they readily sided with the Cataphrygian Christians, and established that Christianity before the end of the fourth century. By this means those of understanding, after they had been persecuted by the heathen Emperors in the three first centuries, and were holpen with a little help, by the conversion of Constantine the great and his sons to the Christian religion, fell under new persecutions, to purge them from the dissemblers, and to make them white, even to the time of the end.

It is inconceivable that inanimate brute matter should, without the mediation of something else which is not material, operate upon and affect other matter without mutual contact, as it must be, if gravitation in the sense of Epicurus, be essential and inherent in it. And this is one reason why I desired you would not ascribe innate gravity to me. That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity that I believe no man who has in philosophical matters a competent faculty of thinking can ever fall into it. Gravity must be caused by an agent acting constantly according to certain laws; but whether this agent be material or immaterial, I have left open to the consideration of my readers.
