We always speak well when we make ourselves understood.[Quand on se sait entendre, on parle toujours bien.]
Two people who know they do not understand each other, breeding children whom they do not understand and who will never understand them.
To what purpose all this, but to shew that the difference so observable in men’s understandings and parts, does not arise so much from natural faculties as acquired habits?
The understanding, like the eye, whilst it makes us see and perceive all other things, takes no notice of itself; and it requires art and pains to set it at a distance and make it its own object.
The theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men.
The evil that is in the world always comes of ignorance, and good intentions may do as much harm as malevolence, if they lack understanding.
