Page 494 - Shot through vast masses of enormous weight ? Who bid brute matter's restive lump assume Such various forms, and gave it wings to fly ? Has matter innate motion ? then each atom, Asserting its indisputable right To dance, would form an universe of dust...
Page 146 - The qualities of bodies, which admit neither intensification nor remission of degrees and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever.
Page 499 - As a blind man has no idea of colors, so have we no idea of the manner by which the all-wise God perceives and understands all things. He is utterly void of all body and bodily figure, and can therefore neither be seen, nor heard, nor touched ; nor ought he to be worshipped under the representation of any corporeal thing. We have ideas of his attributes, but what the real substance of anything is, we know not.
Page 499 - Whence also He is all similar, all eye, all ear, all brain, all arm, all power to perceive, to understand, and to act ; but in a manner not at all human, in a manner not at all corporeal, in a manner utterly unknown to us.
Page 498 - He is eternal and infinite, omnipotent and omniscient; that is, his duration reaches from eternity to eternity; his presence from infinity to infinity; he governs all things, and knows all things that are or can be done.
Page 42 - Seek him that maketh the seven stars and Orion, And turneth the shadow of death into the morning, And maketh the day dark with night: That calleth for the waters of the sea, And poureth them out upon the face of the earth : The Lord is his name: That strengtheneth the spoiled against the strong, So that the spoiled shall come against the fortress.
Page 42 - Ye who turn judgment to wormwood, and leave off righteousness in the earth, seek him that maketh the seven stars and Orion, and turneth the shadow of death into the morning, and maketh the day dark with night; that calleth for the waters of the sea, and poureth them out upon the face of the earth; the Lord is his name; that strengtheneth the spoiled against the strong, so that the spoiled shall come against the fortress.
Page 132 - Systems in many respects resemble machines. A machine is a little system, created to perform, as well as to connect together, in reality, those different movements and effects which the artist has occasion for. A system is an imaginary machine invented to connect together in the fancy those different movements and effects which are already in reality performed.
Page 133 - The machines that are first invented to perform any particular movement are always the most complex, and succeeding artists generally discover that, with fewer wheels, with fewer principles of motion, than had originally been employed, the same effects may be more easily produced.
