“Barriers of sea, or desert, or mountain, could never have been of the least avail, had the creative force acted independently of material laws, or had it not pleased the Author of Nature that the origin of new species should be governed by some secondary causes analogous to those which we see preside over the appearance of new varieties, which never appear except as the offspring of a parent stock very closely resembling them.”

“The passive strength of materials of all kinds has been very fully investigated, and many new conclusions have been formed respecting it, which are of immediate importance to the architect and to the engineer, and which appear to contradict the results of some very elaborate calculations.”

Thomas Young (scientist) (1773–1829) English polymath

“Lastly, isolation, by checking immigration and consequently competition, will give time for any new variety to be slowly improved; and this may sometimes be of importance in the production of new species. If, however, an isolated area be very small, either from being surrounded by barriers, or from having very peculiar physical conditions, the total number of the individuals supported on it will necessarily be very small; and fewness of individuals will greatly retard the production of new species through natural selection, by decreasing the chance of the appearance of favourable variations.”

“The conflict between liberty under divine authority and the absolutism of human authorities ended disastrously. …In the very year 586 [BCE], in which the flood of Asiatic despotism closed over the city which had been, and was destined again to be, the sanctuary of freedom in the East, a new home was prepared for it in the West, where, guarded by the sea and the mountains, and by valiant hearts, that stately plant was reared under whose shade we dwell, and which is extending its invincible arms so slowly and yet so surely over the civilised world.”

“It is willingly granted that by cultivation the origination of new varieties is favored, and that by man's labor many varieties are acquired which, under natural conditions, would be lost; but nothing justifies the assumption that the tendency to formation of varieties is so extraordinarily increased that the species speedily lose all stability, and their offspring diverge into an endless series of extremely variable forms. Were the change in the conditions the sole cause of variability we might expect that those cultivated plants which are grown for centuries under almost identical conditions would again attain constancy.”

“The Egyptian philosophers ventured on the perilous task of seeking out some analogy to the mode of operation employed by the Author of Nature in the first creation of organized beings, and they compared it to that which governs the birth of new individuals by generation.”

“It had never occurred to me that our lives, which had been so closely interwoven, could unravel with such speed.”

Kazuo Ishiguro (1954) Japanese-born British author

“Their lordships had some experience in that House two years ago, when restrictive laws were passed and when the Habeas Corpus Act was suspended…The effect of these measures was, in his opinion, the cause of a great portion of the discontent which now prevailed. After all the experience which they had had, there was no attempt at conciliation, no concession to the people; nothing was alluded to but a resort to coercion…The natural consequence of such a system, when once begun, was that it could not be stopped: discontents begot the necessity of force; the employment of force increased discontents: these would demand the exercise of new powers, till by degrees they would depart from all the principles of the constitution…Could government rest with confidence upon the sword for security? It was impossible that a government of such a nature could exist in England…without that spirit which the knowledge of the advantages they enjoyed under their constitution infused, all their energies would flag, and all their feelings by which their glory as a nation had been established, would be utterly dissipated.”

Charles Grey, 2nd Earl Grey (1764–1845) Prime Minister of the United Kingdom of Great Britain and Ireland

Speech in the House of Lords (23 November 1819). Parliamentary Debates, vol. xli, pp. 7-19, quoted in Alan Bullock and Maurice Shock (ed.), The Liberal Tradition from Fox to Keynes (Oxford: Clarendon Press, 1967), pp. 5-6.

“It is not here necessary to examine in detail the causes which led to the American Revolution. In their immediate occasion they were largely economic. The colonists objected to the navigation laws which interfered with their trade, they denied the power of Parliament to impose taxes which they were obliged to pay, and they therefore resisted the royal governors and the royal forces which were sent to secure obedience to these laws. But the conviction is inescapable that a new civilization had come, a new spirit had arisen on this side of the Atlantic more advanced and more developed in its regard for the rights of the individual than that which characterized the Old World. Life in a new and open country had aspirations which could not be realized in any subordinate position. A separate establishment was ultimately inevitable. It had been decreed by the very laws of human nature. Man everywhere has an unconquerable desire to be the master of his own destiny.”

Calvin Coolidge (1872–1933) American politician, 30th president of the United States (in office from 1923 to 1929)

1920s, Speech on the Anniversary of the Declaration of Independence (1926)

“The only secondary cause… which has, as yet, been even conjecturally brought forward, to explain how, in the ordinary course of nature, a new specific form may be generated is, as Lamarck declared, 'variation,' and this has been rendered a far more probable hypothesis by the way in which Natural Selection is shown to give intensity and permanency to certain varieties.”
