“The limits of my language are the limits of my universe.”

“Man is not born to solve the problem of the universe, but to find out what he has to do; and to restrain himself within the limits of his comprehension.”

“The limits of my language means the limits of my world.”

“Two souls alas! are dwelling in my breast”

“To be pleased with one's limits is a wretched state.”

“I know I can trust in my heart…that she…dare I, can I express heaven in a few words? That she loves me.”

“How clearly I have seen my condition, yet how childishly I have acted. How clearly I still see it, and yet show no sign of improvement.”
