Abstract

A distinction must be made between various levels of thought. For a definition of life the formulation on the level of natural sciences,i.e. the biological definition, will not be the same as the philosophical expression. The biological definition is based on thephenomenon of life, the appearance, and considers the molecular structure and functions of a cell. The philosophical definition regards thebeing and it is proposed to consider life as transcendental. It is argued that there is no opposition between these definitions, but that together they can deepen our insight into the problems of matter and life
