Famous quotes containing the word species:
“The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.”
—Freeman Dyson (b. 1923)
“Thus all probable reasoning is nothing but a species of sensation. Tis not solely in poetry and music, we must follow our taste and sentiment, but likewise in philosophy, When I am convincd of any principle, tis only an idea which strikes more strongly upon me. When I give the preference to one set of arguments above another, I do nothing but decide from my feeling concerning the superiority of their influence.”
—David Hume (17111776)
