“To Make a book, my children, there is double work: first the labor of the one who thinks and writes it and then the one labor of the one who prints it. To think a book and write it under the sole dictation of one’s mind is a difficult and serious business. Brain work exhausts our strength much more quickly than manual labor, for we must put the best of ourselves into it, our soul. I tell you these things that you may see what gratitude you owe those who, solicitous for your future, think and write in order to teach you to think for yourselves and to free you from the miseries of ignorance.”
-Jean Henri Fabre (Story Book of Science page 55)
