In the early part of my academic career I dabbled in philosophy, particularly the philosophies of Kant and Hegel. But as I matured, I came to my senses. This explains why during the last 15 years I have devoted much more attention to evidence, inference, and proof in litigation than to German Idealism and similar matters. However, I did not succeed in completely obliterating the influence of philosophy and epistemology on my thinking. Thus, in my effort to understand and explain the process of proof in litigation, I have devoted a great deal of attention to matters such as probability theory and theories of evidence, inference, induction, and proof.
