“So long as physiologists continued to believe that man had not existed on the earth above six thousand years, they might, with good reason, withhold their assent from the doctrine of a unity of origin of so many distinct races; but the difficulty becomes less and less, exactly in proportion as we enlarge our ideas of the lapse of time during which different communities may have spread slowly, and become isolated, each exposed for ages to a peculiar set of conditions, whether of temperature, or food, or danger, or ways of living.”

“[one watercolor] is in spite of all its difficulties, and perhaps because she has given so much trouble, less fresh and has become a little heavy - I myself have considered for a long time whether she was good enough to send it [for a exhibition in Utrecht] (translation from original Dutch: Fons Heijnsbroek)”

(original Dutch: citaat van Willem Roelofs, in het Nederlands:) [een aquarel] is niettegenstaanden alle moeite, en misschien wel omdàt zij moeite heeft gekost, minder frisch en wat zwaar geworden – Ik heb zelf lang in beraad gestaan of zij goed genoeg was om te zenden [naar Utrecht]

“If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course of untold millions of years, give origin to the human race.”
