Entry 0232: Existence and Non-Contradiction
1. An existing thing, by the very fact that it exists, excludes its simultaneous non-existence.
2. “Let us consider any being. That being, by the very fact that it exists, cannot simultaneously not exist. Its very existence excludes its simultaneous non-existence” (Jose Sanchez Villasenor, Ortega y Gasset Existentialist: A Critical Study of His Thought and Its Sources, trans. Joseph Small [Chicago: Henry Regnery Company, 1949], 205).
3. An existing thing manifests its existence.
4. “The existence of a thing implies the manifestation of its existence” (Paul Carus, Fundamental Problems: The Method of Philosophy as a Systematic Arrangement of Knowledge [Chicago: The Open Court Publishing Company, 1903], 155).
5. Everything that exists manifests its existence somehow. No matter how hard it is for us to get to know the existence of a thing, an existing thing cannot hide its existence.
6. “Each individual thing manifests its own existence clearly” (http://gudoblog-e.blogspot.com/2008_11_01_archive.html, accessed 30 June 2012).
7. It is self-evident that things actually present to our external senses are real existing things.
