Question

"Why should that apple always descend perpendicularly to the ground, thought [Newton] to himself; occasioned by the fall of an apple, as he sat in a contemplative mood. Why should it not go sideways, or upwards? But constantly to the earth's center? Assuredly, the reason is, that the earth draws it. There must be drawing power in matter... If matter thus draws matter; it must be in proportion of its quantity. Therefore, the apple draws the earth, as well as the earth draws the apple." - Memoirs of Sir Isaac Newtown's Life, William Stukeley
