Philosophers are generally persuaded, that the sensations of heat and cold are occasioned by the presence or absence, in degree, of certain principle or quality denominated fire or heat... It is most probable, that all substances whatever contain more or less of this principle. Respecting the nature of the principle, however, there is a diversity of sentiment : some supposing it a substance, others a quality, or property of substance. Boerhaave, followed by most of the moderns, is of the former opinion; Newton, with some others, are of the latter; these conceive heat to consist in an internal vibratory motion of the particles of bodies.

There are things which we feel to be good and true, though in the cold light of reason and calculation many things remain incomprehensible and dark. And though the society in which we live considers such actions thoughtless, or reckless, or I don't know what else, what can we say if once the hidden forces of sympathy and love have been roused in us? And though it may be that we cannot argue against the reasoning sentiment and to act from impulse, one would almost conclude that some people have cauterized certain sensitive nerves within them, especially those which, combined, are called conscience. Well, I pity those people; they travel through life without compass, in my opinion.

If the water flow down by a gradual natural channel, its potential energy is gradually converted into heat by fluid friction, according to an admirable discovery made by Mr Joule of Manchester above twelve years ago, which has led to the greatest reform that physical science has experienced since the days of Newton. From that discovery, it may be concluded with certainty that heat is not matter, but some kind of motion among the particles of matter; a conclusion established, it is true, by Sir Humphrey Davy and Count Rumford at the end of last century, but ignored by even the highest scientific men during a period of more than forty years.

Men fall, roughly speaking, into two flocks: Those whose intelligence is uninquiring in the face of Art, and does not demand to be appeased before their emotions can be stirred; and those who, having a speculative bent of mind, must first be satisfied by an enlightening quality in a work of Art, before that work of Art can awaken in them feeling. The audience of the realist is drawn from this latter type of man; the much larger audience of the romantic artist from the former; together with, in both cases, those fastidious few for whom all Art is style and only style, and who welcome either kind, so long as it is good enough.

To dissimulate is to pretend not to have what one has. To simulate is to feign to have what one doesn't have. One implies a presence, the other an absence. But it is more complicated than that because simulating is not pretending: "Whoever fakes an illness can simply stay in bed and make everyone believe he is ill. Whoever simulates an illness produces in himself some of the symptoms" (Littré). Therefore, pretending, or dissimulating, leaves the principle of reality intact: the difference is always clear, it is simply masked, whereas simulation threatens the difference between the "true" and the "false," the "real" and the "imaginary."

The lower classes of people in Europe may at some future period be much better instructed then they are at present; they may be taught to employ the little spare time they have in many better ways than at the ale-house; they may live under better and more equal laws than they have hitherto done, perhaps, in any country; and I even conceive it possible, though not probable, that they may have more leisure; but it is not in the nature of things, that they can be awarded such a quantity of money or substance, as will allow them all to marry early, in the full confidence that they shall be able to provide with ease for a numerous family.
