“the concept of a distinctively human, normal, or well-functioning personality is rooted in psychosocial and ethical criteria. It is not biologically given, nor are biological determinants especially significant for it. I do not deny, of course, that man is an animal with a genetically determined biological equipment which sets the upper and lower limits within which he must function. I accept the limits, or the general range, and focus on the development of specific patterns of operation within them. Hence, I eschew biological considerations as explanations, and instead try to construct a consistently moral and psychosocial explanatory scheme.
Clearly, different societies exhibit different values. And even within a single society, especially if it is composed of many individuals, adults and growing children have certain choices about which values to teach and which to accept or reject. In contemporary Western societies, one of the principal alternatives is between autonomy and heteronomy, between "risky" freedom and "secure" slavery.”
