Famous quotes containing the words basic and/or concepts:

    “When you realize how hard it is to know the truth about yourself, you understand that even the most exhaustive and well-meaning autobiography, determined to tell the truth, represents, at best, a guess. There have been times in my life when I felt incredibly happy. Life was full. I seemed productive. Then I thought,”Am I really happy or am I merely masking a deep depression with frantic activity?” If I don’t know such basic things about myself, who does?”
    —Phyllis Rose (b. 1942)

    “Germany collapsed as a result of having engaged in a struggle for empire with the concepts of provincial politics.”
    —Albert Camus (1913–1960)
