# Theory of everything (philosophy) | | In philosophy, a theory of everything (ToE) is an ultimate, all-encompassing explanation or description of nature or reality. Adopting the term from physics, where the search for a theory of everything is ongoing, philosophers have discussed the viability of the concept and analyzed its properties and implications. Among the questions to be addressed by a philosophical theory of everything are: "Why is reality understandable?" – "Why are the laws of nature as they are?" – "Why is there anything at all?" | |-|-| | | wikipedia:: [Theory of everything (philosophy)](https://en.wikipedia.org/wiki/Theory_of_everything_(philosophy)) |
