“Let every man in mankind's frailty consider his last day; and let none presume on his good fortune until he find Life, at his death, a memory without pain.”

“When it shall be desired to enlighten man, let him always have truth laid before him. Instead of kindling his imagination by the idea of those pretended goods that a future state has in reserve for him, let him be solaced, let him be succoured; or, at least, let him be permitted to enjoy the fruit of his labour; let not his substance be ravaged from him by cruel imposts; let him not be discouraged from work, by finding all his labour inadequate to support his existence, let him not be driven into that idleness that will surely lead him on to crime: let him consider his present existence, without carrying his views to that which may attend him after his death: let his industry be excited; let his talents be rewarded; let him be rendered active, laborious, beneficent, and virtuous, in the world he inhabits; let it be shown to him that his actions are capable of having an influence over his fellow men, but not on those imaginary beings located in an ideal world.”

“Let every man be his own methodologist, let every man be his own theorist”

“Happiness consists more in the small conveniences of pleasures that occur every day, than in great pieces of good fortune that happen but seldom to a man in the course of his life.”

“For him that stealeth, or borroweth and returneth not, this book from its owner, let it change into a serpent in his hand and rend him. Let him be struck with palsy, and all his members blasted. Let him languish in pain, crying aloud for mercy, and let there be no surcease to this agony till he sing in dissolution. Let bookworms gnaw his entrails in token of the worm that dieth not, and when at last he goeth to his last punishment, let the flames of hell consume him for ever.Curse on book thieves, from the monastery of San Pedro, Barcelona, Spain”

“Let the man who has to make his fortune in life remember this maxim. Attacking is his only secret. Dare, and the world always yields: or, if it beat you sometimes, dare again, and it will succumb.”
