The questions, if and how life has emerged via chemical evolution (CE) requires at first a definition of the goal of the evolution, a definition of life. However, in this regard, the Austrian writer A. Schnitzler was extremely skeptic and wrote: “Was Leben ist, vermag kein Wissenschaftler zu sagen” (No scientist is able to define the meaning of life). Nonetheless, numerous scientists have attempted to find a definition for the phenomenon called life, and the author is not ambitious to present a new definition, but prefers to present a short summary of the various attempts made by renowned scientists and philosophers. A detailed discussion of this topic may be found in publications of the following authors: Bernal (1951, 1967, 1971), Folsom (1979), Chyba and McDonalds (1995), Rizzoti (1996), Palyi et al. (2002), Popa (2004), and Luisi (2006).

摘要

The questions, if and how life has emerged via chemical evolution (CE) requires at first a definition of the goal of the evolution, a definition of life. However, in this regard, the Austrian writer A. Schnitzler was extremely skeptic and wrote: “Was Leben ist, vermag kein Wissenschaftler zu sagen” (No scientist is able to define the meaning of life). Nonetheless, numerous scientists have attempted to find a definition for the phenomenon called life, and the author is not ambitious to present a new definition, but prefers to present a short summary of the various attempts made by renowned scientists and philosophers. A detailed discussion of this topic may be found in publications of the following authors: Bernal (1951, 1967, 1971), Folsom (1979), Chyba and McDonalds (1995), Rizzoti (1996), Palyi et al. (2002), Popa (2004), and Luisi (2006).
