What does it mean to be human? What differentiates us from our forefathers? In which direction is the human race headed? This innovative study attempts to answer these complicated questions and others.

This book is a collection of articles, conversations and lectures that were conceived as a part of Isaiah Leibowitzs study and deliberation on the subject of natural sciences and Humanities. The materials for this collection were compiled from varied sources: other collections, journals, recordings, the Hebrew encyclopedia and more. The book mainly deals with the conflict between "facts" and "values". There are philosophers who see this conflict as the axis on which philosophical thinking circles, in all its courses and in all times: whether it introduces actual duality or just a duality that exists in our consciousness.

Readers of this book, other than those knowledgeable in new developments in microbiology, palethnology and biology, may find themselves surprised at the extent to which the entire biosphere is a single unit, a giant living combined system, one organism.

What is life? What is death? Is the death penalty legitimate still? How does suicide fit in with survival instincts? Researchers representing the natural sciences, humanities, psychology, medicine and law, engage in fundamental questions concerning the nature of life and its value: Life and death; Is there extraterrestrial life; What is the will to live and how to understand suicide; Is there a significance and reason to life ; Perception of life as a biblical faith and Jewish thought; The status of the embryo in ancient times and in our time; The problem of the death penalty in the reality of life in Israel today; Dealing with the Finality of life; And "life after life" according to the Bible. Examining each of these aspects of the concept of 'life' continuously, reveals both the complexity of the subject and the complexity of the human spirit needed for it.
