Context

“Everybody knows the differences which have been observed with regard to this between hot and cold countries, and every one sees that ardent temperaments mature earlier than others; but we may be mistaken as to the causes, and we may often attribute to physical causes what is really due to moral: this is one of the commonest errors in the philosophy of our times. The teaching of nature comes slowly; man's lessons are mostly premature. In the former case, the senses kindle the imagination, in the latter the imagination kindles the senses; it gives them a precocious activity which cannot fail to enervate the individual and, in the long run, the race.” source
