"The highest activity a human being can attain is learning for understanding, because to understand is to be free."

"He alone is free who lives with free consent under the entire guidance of reason"

"I have made a ceaseless effort not to ridicule, not to bewail, not to scorn human actions, but to understand them."

"I do not know how to teach philosophy without becoming a disturber of the peace."

"The highest activity a human being can attain is learning for understanding, because to understand is to be free."
