The best key for the aforesaid analogy, or natural science, will be easily acknowledged to be a certain celebrated treatise of mechanics: in the entrance of which justly admired treatise, time, space and motion, are distinguished into absolute and relative, true and apparent, mathematical and vulgar : which distinction, as it is at large explained by the author, doth suppose those quantities to have an existence without the mind : and that they are ordinarily conceived with relation to sensible things, to which nevertheless in their own nature, they bear no relation at all.

The overall story, as I see it, of how Berkeley stands in relation to the work of these four men is roughly as follows. Malebranche represents an intellectual tradition that stretches back to the scholastics and eventually to St Augustine. Descartes and Locke represents a distinctive philosophical position, informed by the new science. Newton was the new science personified. Berkeley was deeply impressed by Newton's work, and wanted to give it pride of place in his philosophical picture. But he wanted to overtun much of the philosophy of Locke and Descartes, and return as (always still informed by the new science) more nearly to the ways of Malebranche and his tradition.
