الصفحة 48 - ... Faculty of an intellectual Being. For my own part, I look upon it as upon the Principle of Gravitation in Bodies, which is not to be explained by any known Qualities inherent in the Bodies themselves, nor from any Laws of Mechanism, but, according to the best Notions of the greatest Philosophers, is an immediate Impression from the first Mover, and the Divine Energy acting in the Creatures.
الصفحة 45 - ... a powerful ever-living 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 146 - Descartes' absurd theory, of brutes being like machines, which, as far as he holds it, he avows to have proceeded from the notion that unless they are so, their souls would be immortal. But another reason may be assigned. The sceptical, or free-thinking, philosophers always lowered human nature as much as possible. They regarded it as something gained to their arguments against religious belief, if they could show the difference to be slighter than is supposed between men and brutes; and that there...
الصفحة 112 - America, where the wild horse is gregarious, there are herds of five or six hundred, which, being ill-prepared for fighting, or indeed for any resistance, and knowing that their safety is in flight, when they sleep, appoint one in rotation who acts as sentinel, while the rest are asleep. If a man approaches, the sentinel walks towards him as if to reconnoitre or see whether he may be deterred from coming near ; if the man continues, he neighs aloud and in a peculiar tone, which rouses the herd, and...
الصفحة 294 - How much he attended to the subject is, however, manifest from the extent of the first of these chapters, which is of great length. Some mathematical writers, particularly Pappus, studied the form of the cells, and established one or two of the fundamental propositions respecting the economy of labour and wax resulting from the plan of the structure. The application of modern naturalists to the inquiry is to be dated from the beginning of the eighteenth century, when Maraldi examined it with his...
الصفحة 9 - We may go further, and add, that as in plants, where the motions are without animal life, those motions are more perfect and more undisturbed, so if there be any animal wholly without reason, the operations of mental Instinct are the more regular and perfect ; and, in any animal whatever, they are so in proportion as reason is dormant or inactive.
الصفحة 163 - If I am to teach a dog or a pig to do certain things on a given signal, the process I take to be this. I connect his obedience with reward, his disobedience with punishment. But this only gives him the motive to obey, the fear of disobeying. It in no way can give him the means of connecting the act with the sign. Now, connecting the two together, whatever be the manner in which the sign is made, is abstraction ; but it is more, it is the very kind of abstraction in which all language has its origin...
الصفحة 293 - ... fact, they made but little progress in discovering the singular economy of this insect. Of the observations of Aristomachus, who spent sixty years, it is said, in studying the subject, we know nothing ; nor of those which were made by Philissus, who passed his life in the woods, for the purpose of examining this insect's habits ; but Pliny informs us that both of them wrote works upon it. Aristotle's three chapters on bees and wasps* contain little more than the ordinary observations, mixed up...
الصفحة 124 - Instinct mention a cat which had been taken to the West Indies, and on the ship returning to the Port of London she found her way through the city to Brompton, whence she had been brought. B. That is a work I have often wished to see, and never been able to get. Dr. Hancock quotes it for one of the most remarkable proofs of sagacity and resource in the Goat, and this operation has been, it seems, observed more than once. When two Goats meet on a ledge bordering upon a precipice, and find there is...
