“You despise them, books, you whose whole life is plunged in the vanities of ambition and in the search for pleasure or in idleness. [...] It is with books as with men; the very small number play a great part, the rest are mingled in the crowd.”
"Voltaire's Philosophical Dictionary"
“Some books are to be tasted, others to be swallowed, and some few to be chewed and digested: that is, some books are to be read only in parts; others to be read, but not [with great care]; and some few to be read wholly and with diligence and attention.”
"The Essays" by Francis Bacon (1625)
