Species Concept

Famous quotes containing the words species and/or concept:

“Any reading not of a vicious species must be a good substitute for the amusements too apt to fill up the leisure of the labouring classes.”

“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
