Famous quotes containing the words study and/or species:
“If we study nature attentively, alike in its great revolutions and in its minutest works, it is impossible not to admit enchantment—giving the word its fullest meaning. Man can create no force; he can but use the only existing force, which includes all others, namely, Motion—the incomprehensible Breath of the sovereign maker of the universe.”
—Honoré De Balzac (1799–1850)
“The further our civilization advances upon its present lines so much the cheaper sort of thing does “fame” become, especially of the literary sort. This species of “fame” a waggish acquaintance says can be manufactured to order, and sometimes is so manufactured.”
—Herman Melville (1819–1891)
