All behavior is motivated by some form of drive reduction.
The passions that incline men to peace are fear of death, desire of such things as are necessary to commodious living, and a hope by their industry to obtain them.
——〈民权主义第五讲〉，1924年4月20日
"To be human is to be flawed, and to be flawed is to be real."
我不是一个完美的人，但我是一个真实的人。
