Nor did he feel that this force was proportional to the inverse of the square of the distance between the centres of mass of the two bodies, and directly proportional to the product of the masses of the two bodies.[^1] Rather he perceived the stone as it came down towards the ground and the moon rotating around the earth and the planets around the sun.
He pondered all this and endeavoured to interpret these phenomena, relying on Galileo's theory of the uniform acceleration of bodies falling or rolling down inclined planes.[^2] He likewise made use of Keppler's laws of planetary motion, the third of which states, “The Square of the period of rotation of a planet around the sun is proportional to the cube of its distance from it.”[^3]In the light of all this Newton discovered the law of gravity.
He supposed that, “A gravitational force of attraction between two particles is always determined by the masses and the distance between them. “[^4] It should have been possible. for this empirical trend as a method of investigating the order of the universe to present a new and illuminating argument in support of faith in God, exalted be He.
This should have been possible, in view of the fact that this method has uncovered aspects of harmony in the universe which can be used as proofs of an intelligent and wise Creator. Scientists, in as much as they are concerned with natural phenomena, have not interested themselves with the clarification of this problem, which has for long been considered as a metaphysical matter outside the scope of strictly scientific concern.
Soon, however, new directions appeared within the discipline of philosophy, outside the scope of natural science, which endeavoured to “philosophize” this empirical, method and present it in the terminology of formal logic. This new philosophy declared that the only means of knowledge is sense experience, and where sense perception ends human knowledge ceases. Thus whatever is inaccessible to the senses and cannot, be verified by direct experimentation, cannot be proved by any other means.
This empirical and experimental trend was used to counter the idea of faith in God, the Exalted. Since God is not a being subject to sense experience, capable of being seen and felt, there is no way of proving His existence.
