Σελίδα 278 - Secondly, such qualities which in truth are nothing in the objects themselves but powers to produce various sensations in us by their primary qualities, ie by the bulk, figure, texture, and motion of their insensible parts, as colours, sounds, tastes, &c.
Σελίδα 384 - Have not the small particles of bodies certain powers, virtues, or forces by which they act at a distance, not only upon the rays of light for reflecting, refracting, and inflecting them, but also upon one another for producing a great part of the phenomena of nature?
Σελίδα 429 - All these things being considered, it seems probable to me that God, in the beginning, formed matter in solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties, and in such proportions to space, as most conduced to the end for which He formed them...

But other •' men, unaware of this masquerade, hold it to be a fact that " they see cubes and spheres, spacious apartments and winding " avenues.
