道德問題
I shall define him as an individual who has elected as his primary duty and pleasure in life the activity of thinking in Socratic way about moral problems.
譯文我會把他定義為一個對道德問題進行蘇格拉底式思考，并將此作為自己人生首要責任和樂趣的人。
點睛
define sth./sb. as....意為“把某事物/某人定義/解釋為…”。who引導的是以individual為先行詞的定語從句，其中the activity of_為賓語，介詞短語as...in life是其補語。elect此處意為“選擇”，而非“選舉”。
