Self-evident proposition means a principle which requires no proof or explanation. For instance, it is a self evident proposition, that no man in a state can be deprived of liberty or property, but by the law of the land or the judgment of his peers. And it is a self-evident proposition that a dead man can neither create obligations nor authorize others to create them for him. Further, it is a self-evident proposition, that where the law declares a contract to be void, a party can acquire no legal right under or by virtue of it. To a self-evident proposition the mind assents without hesitation.
