Famous quotes containing the words single and/or species:
“[The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.”
—Henry Brooks Adams (18381918)
“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)
