We are a free people; and now you have planted in our country the title deeds of our future slavery. You are neither god nor demon; who are you, then, to make slaves? Orou! You understand the language of these men, tell us all, as you have told me, what they have written on this sheet of metal: This country is ours. This country yours? And why? Because you have walked thereon? If a Tahitian landed one day on your shores, and scratched on one of your rocks or on the bark of your trees: This country belongs to the people of Tahiti - what would you think?
Denis DiderotI picture the vast realm of the sciences as an immense landscape scattered with patches of dark and light. The goal towards which we must work is either to extend the boundaries of the patches of light, or to increase their number. One of these tasks falls to the creative genius; the other requires a sort of sagacity combined with perfectionism.
Denis DiderotThe philosopher forms his principles on an infinity of particular observations. He does not confuse truth with plausibility, he takes for truth what is true, for false what is false, for doubtful what is doubtful, and probable what is probable. The philosophical spirit is thus a spirit of observation and accuracy.
