Página 64 - The only proof capable of being given that an object is visible, is that people actually see it. The only proof that a sound is audible, is that people hear it: and so of the other sources of our experience. In like manner, I apprehend, the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it.
Página 173 - General observations drawn from particulars are the jewels of knowledge, comprehending great store in a little room; but they are therefore to be made with the greater care and caution, lest, if we take counterfeit for true, our loss and shame be the greater when our stock comes to a severe scrutiny.
Página 484 - It would be no less impracticable to think of wholly annihilating the popular assemblies in which these lawyers sit. The army, by which we must govern in their place, would be far more chargeable to us; not quite so effectual ; and perhaps, in the end, full as difficult to be kept in obedience. With regard to the high aristocratic spirit of Virginia and the southern colonies, it has been proposed, I know, to reduce it, by declaring a general enfranchisement of their slaves.
Página 486 - Matters of fact, which are the second objects of human reason, are not ascertained in the same manner; nor is our evidence of their truth, however great, of a like nature with the foregoing. The contrary of every matter of fact is still possible; because it can never imply a contradiction, and is conceived by the mind with the same facility and distinctness, as if ever so conformable to reality.
Página 68 - No reason can be given why the general happiness is desirable, except that each person, so far as he believes it to be attainable, desires his own happiness. This, however, being a fact, we have not only all the proof which the case admits of, but all which it is possible to require, that happiness is a good : that each person's happiness is a good to that person, and the general happiness, therefore, a good to the aggregate of all persons.
Página 272 - It must be granted that in every syllogism, considered as an argument to prove the conclusion, there is a petitio principii. When we say, All men are mortal, Socrates is a man, therefore Socrates is mortal...
Página 42 - Guido, with a burnt stick in his hand, demonstrating on the smooth paving-stones of the path, that the square on the hypotenuse of a right-angled triangle is equal to the sum of the squares on the other two sides.
Página 187 - Some mechanicians attempt to prove (what they ought to lay down as a probable but doubtful hypothesis*) that every particle of matter gravitates equally : 'why?' 'because those bodies which contain more particles ever gravitate more strongly, ie are heavier :' ' but, (it may be urged,) those which are heaviest are not always more bulky...
Página 451 - In a given state of society, a certain number of persons must put an end to their own life. This is the general law; and the special question as to who shall commit the crime depends of course upon special laws; which, however, in their total action, must obey the large social law to which they are subordinate. And the power of the larger law is so irresistible, that neither the love of life nor the fear of another world can avail anything towards even checking its operation.
Página 188 - We may be quite sure that the acquirement of those classes of facts which are most useful for regulating conduct involves a mental exercise best fitted for strengthening the faculties. It would be utterly contrary to the beautiful economy of nature if one kind of culture were needed for the gaining of information and another kind were needed as a mental gymnastic.
