In 2005 Lenn E. Goodman, along with John Hare, Abdulaziz Sachedina and A.C. Grayling, delivered the Gifford Lectures at the University of Glasgow on the topic "Thou shalt love thy neighbor as thyself." Professor Goodman, approaching the topic from the perspective of Jewish philosophy, published his lectures.
In his first lecture Professor Goodman seeks to put the commandment in the broad context of the Hebrew Bible and in the context of rabbinic tradition. His second lecture attempts to answer the question as to the relationship between ethics and God. Dr. Goodman's thesis is that "We learn about God through our ethical understanding and we learn about ethics through our understanding of God."
