Thoreau writes that people should be "mining themselves for gold".By this he is stating in another way the ideal of Socrates which was to

A.deny thyself to learn what is valiable
B.live and let live
C.put first things first
D.know thyself

my answer is B

I disagree.

Socrates was noted for telling men to "know thyself."

D is the right answer

Know thyself

D. Know thyself

Actually, the correct answer is D. "Know thyself." Thoreau's statement about people mining themselves for gold is a metaphorical way of expressing the idea that individuals should engage in deep self-reflection and self-examination in order to discover their true essence or potential. This idea aligns closely with Socrates' philosophy of "know thyself." Socrates believed that self-knowledge and introspection were essential for personal growth and understanding one's place in the world. Thus, Thoreau's statement is another way of expressing the same ideal as Socrates' notion of knowing oneself.
