Abstract

Plato placed great importance on the natural number one. Plato stated that the three properties of Plato’s one are indivisible, invariable, and equal and that an ideal one has no physical properties. If we regard differences among lives as differences among genes and gene products and life as the container of genes, then life has properties similar to Plato’s one. Furthermore, life has properties of multiplying when it survives and disappearing when it dies. These properties of life are prerequisites for natural selection. Natural selection makes DNA become digital information, enabling accurate copies of DNA. Furthermore, DNA bases, essential for survival, become close to Plato’s one by natural selection. In addition, the information content of life must be sufficiently large for death to be irreversible, and the irreversibility of death is a prerequisite for natural selection.
