Abstract
The study of the origin and nature of life can be a problem, especially for a scientist whose method precludes any conclusion that would transcend the realm of empirical evidence. A scientist, and more specifically a biologist, can ascertain the characteristics that distinguish a living from a non-living being, but he is unable to attain to the source of those characteristics or life itself, which defies all empirical analysis. Here science must surrender to philosophy and let reason draw conclusions that go beyond the data of experience and reach out into an area that many philosophers consider as their exclusive domain.
