“It may be objected that a man cannot subsist in the sun; but does it follow from thence, that God cannot or has not constituted a nature peculiar to that fiery region, and caused it to be as natural and necessary for it to suck in and breathe out flames of fire, as it is for us to do the like in air.”

“Men may change their climate, but they cannot change their nature. A man that goes out a fool cannot ride or sail himself into common sense.”

Joseph Addison (1672–1719) politician, writer and playwright

“Sunshine does not cease to warm you because you may not know anything of the constitution of the sun. Fire does not cease to burn you, because, unknowing its fierceness, you thrust your hand into the flame. It is the security of human life and human progress that the laws of nature are ever working and carrying us on with them, whether we know of them or not. But if we know them, we gain a great advantage.”

Annie Besant (1847–1933) British socialist, theosophist, women's rights activist, writer and orator

“If you could breathe a breath so strong you could blow out the wolf. Like you blow out the copo. Like you blow out the fire from the candela. The wolf is made the way the world is made. You cannot touch the world. You cannot hold it in your hand for it is made of breath only.”

Cormac McCarthy book The Crossing

“God, to breathe. Air. You don’t know what it means until you cannot take a breath”

Alice Borchardt book The Dragon Queen

“Fir: it contains a great deal of air and fire with very little moisture and the earthy, so that, as its natural properties are of the lighter class, it is not heavy. Hence, its consistence being naturally stiff, it does not easily bend under the load, and keeps its straightness when used in the framework. But it contains so much heat that it generates and encourages decay, which spoils it; and it also kindles fire quickly because of the air in its body, which is so open that it takes in fire and so gives out a great flame.”

Vitruvius book De architectura

“Unless a man enters upon the vocation intended for him by nature, and best suited to his peculiar genius, he cannot succeed.”

P.T. Barnum (1810–1891) American showman and businessman

“Nature, they say, doth dote,
And cannot make a man
Save on some worn-out plan,
Repeating us by rote.”

James Russell Lowell (1819–1891) American poet, critic, editor, and diplomat

“Although to penetrate into the intimate mysteries of nature and thence to learn the true causes of phenomena is not allowed to us, nevertheless it can happen that a certain fictive hypothesis may suffice for explaining many phenomena.”
Quanquam nobis in intima naturae mysteria penetrare, indeque veras caussas Phaenomenorum agnoscere neutiquam est concessum: tamen evenire potest, ut hypothesis quaedam ficta pluribus phaenomenis explicandis aeque satisfaciat, ac si vera caussa nobis esset perspecta.

Leonhard Euler (1707–1783) Swiss mathematician

“LABOUR, like all other things which are purchased and sold, and which may be increased or diminished in quantity, has its natural and its market price. The natural price of labour is that price which is necessary to enable the labourers, on with another, to subsist and to perpetuate their race, without either increase or diminution.”

David Ricardo (1772–1823) British political economist, broker and politician
