الصفحة 214 - We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes.
الصفحة 284 - ... the main business of natural philosophy is to argue from phenomena without feigning hypotheses and to deduce causes from effects till we come to the very first cause, which certainly is not mechanical; and not only to unfold the mechanism of the world, but chiefly to resolve these and such like questions.
الصفحة 306 - ... all those bodies which compose the mighty frame of the world, have not any subsistence without a mind, that their being is to be perceived or known ; that consequently so long as they are not actually perceived by me, or do not exist in my mind or that of any other created spirit, they must either have no existence at all, or else subsist in the mind of some eternal spirit...

And therefore I scruple not to propose the principles of motion above mentioned, they being of very general extent, and leave their causes to be found out.
الصفحة 285 - WHEN I wrote my treatise about our system, I had an eye upon such principles as might work with considering men for the belief of a Deity ; and nothing can rejoice me more than to find it useful for that purpose.
الصفحة 259 - ... a powerful everliving Agent; who, being in all places, is more able by his will to move the bodies within his boundless uniform sensorium, and thereby to form and reform the parts of the universe, than we are by our will to move the parts of our own bodies.
الصفحة 9 - Brief and powerless is Man's life ; on him and all his race the slow, sure doom falls pitiless and dark. Blind to good and evil, reckless of destruction, omnipotent matter rolls on its relentless way...
الصفحة 8 - Within its depths I saw ingathered, bound by love in one volume, the scattered leaves of all the universe; substance and accidents and their relations, as though together fused, after such fashion that what I tell of is one simple flame.
الصفحة 229 - All these things being considered, it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties and in such proportion to space as most conduced to the end for which he formed them...
