Evolution in... cases has clearly been a very slow and almost (if not quite) continuous process, exactly as Darwin had predicted. We must remember, however, that the organisms studied in this way are far from representative. They are in general the most successful members of animal associations living in very constant marine or lacustrine environments. We have not got similar data for land species... Nor do we possess them for the rarer forms. We shall see... that perhaps dominant species in a uniform environment are the least likely to undergo sudden change to a new type.

A man builds a house in England with the expectation of living in it and leaving it to his children; while we shed our houses in America as easily as a snail does his shell. We live a while in Boston, and then a while in New York, and then, perhaps, turn up at Cincinnati. Scarcely any body with us is living where they expect to live and die. The man that dies in the house he was born in is a wonder. There is something pleasant in the permanence and repose of the English family estate, which we, in America, know very little of.
Harriet Beecher Stowe
Breathes there the man, with soul so dead, Who never to himself hath said, This is my own, my native land Whose heart hath neer within him burnd, As home his footsteps he hath turnd From wandering on a foreign strand If such there breathe, go mark him well For him no Minstrel raptures swell High though his titles, proud his name, Boundless his wealth as wish can claim Despite those titles, power, and pelf, The wretch, concentred all in self, Living, shall forfeit fair renown, And, doubly dying, shall go down To the vile dust, from whence he sprung, Unwept, unhonord, and unsung.
Walter Scott
Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. Not all things are black nor all things white. It is a fundamental of taxonomy that nature rarely deals with discrete categories. Only the human mind invents categories and tries to force facts into separated pigeon-holes. The living world is a continuum in each and every one of its aspects. The sooner we learn this concerning human sexual behavior, the sooner we shall reach a sound understanding of the realities of sex.
Alfred Kinsey
It is a fearful thing to hate whom God hath loved. To look upon another-his weaknesses, his sins, his faults, his defects is to look upon one who is suffering. He is suffering from negative passions, from the same sinful human corruption from which you yourself suffer. This is very important: do not look upon him with judgmental eyes of comparison, noting the sins you assume you'd never commit. Rather, see him as a fellow sufferer, a fellow human being who is in need of the very healing of which you are in need. Help him, love him, pray for him do unto him as you would have him do unto you.
Tikhon of Zadonsk
Darwin believed that the crossing of two types generally led to a blend, and that consequently bisexual reproduction tended to make a species uniform. He therefore had to postulate some cause constantly at work to keep up the inheritable variation within a species. He very naturally looked to the effects of differences of environment. ...It was shown that Darwin had been wrong in supposing that variations due to environment were inheritable. Selection merely picked out the best available line from a given population, and would not, as Darwin had believed, give rise to an unlimited amount of change.
