“I had [...]during many years followed a golden rule, namely, that whenever apublished fact, a new observation or thought came across me, whichwas opposed to my general results, to make a memorandum of itwithout fail and at once; for I had found by experience that such factsand thoughts were far more apt to escape from the memory thanfavorable ones. Owing to this habit, very few objections were raisedagainst my views, which I had not at least noticed and attempted toanswer.” (Darwin 1958, 123)
