One funny Italian expression is from the great Italian scientist and philosopher Galileo Galileii, who said “Non puoi insegnare niente a un uomo. Puoi solo aiutarlo a scoprire ciò che ha dentro di sé,” which means that no one can teach a man anything, because he must find it within himself. Another humorous saying is “il letto e l’opera del povero,” which translates to "bed is the poor man's opera."
Galileo's observation refers to the fact that man is incapable of learning without looking inward and that true learning occurs through a process of self-discovery and awareness that enables man to pursue learning on his own. The English equivalent of this saying is the expression that compares feeding a man a fish versus teaching a man to fish.
The saying “il letto e l’opera del povero,” or “bed is the poor man’s opera” means that a poor man works so hard and has little energy or appreciation for anything other than sleep. It can have a derogatory meaning that the a poor and uneducated person lacks the sophistication or ability to enjoy or appreciate anything but sleep and sex. Additionally, it can have a more optimistic or less derogatory meaning that even the poorest man who cannot afford a night out on the town can enjoy the simplicity of sleeping or sex.
