<p>'Soren Kierkegaard&#39;s <em>Purity of Heart Is to Will One Thing</em> fell into my hands when I was twenty years old. I was traveling alone, seeing Europe for the first time, and being without a great deal of money, was not seduced by the sensuous pleasures of the Parisian world.&nbsp; I had found a paperback English translation on sale in a bin of used books outside a bookshop.&nbsp; <em>Purity&nbsp; of&nbsp; Heart </em>&nbsp;became one of&nbsp; the&nbsp; two or&nbsp; three most&nbsp; important&nbsp; books of&nbsp; my life.&rdquo;</p><p>&ldquo;I felt myself become the individual to whom Kierkegaard was speaking, and in this stirring to life in the center of my being, I realized for the first time consciously what I now call conscience. For me, conscience is much more than the internalized pressure of parents and society to conform to certain arbitrary norms. It&nbsp; is influenced&nbsp; and shaped&nbsp; by&nbsp; culture&nbsp; and&nbsp; society,&nbsp; as&nbsp; we&nbsp; shall&nbsp; see&nbsp; in&nbsp; these&nbsp; explorations, but&nbsp; its roots lie much deeper and&nbsp; its meaning&nbsp; is more&nbsp; transcendent and fateful.' &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; [From the Preface]</p><p>Murray Stein, using case studies from his clinical practice, examples of well-known persons, and Greek legend and mythology, illustrates the distinction between two poles of conscience - one firmly embedded in the community of humankind, the other reaching out to the universe as a whole.</p><p><strong>Murray Stein, Ph.D.</strong> is a supervising training analyst and former president of The International School of Analytical Psychology in Zurich, Switzerland (ISAP Zurich).
