Using this as a means to find an answer to the question of what it means to exist, the thesis is treated as a principle, which sets up a specific, unorthodox kind of defense. Following a Kantian line of thinking, this principle is first interpreted, then and compared to alternatives, upon which finally the specific, concrete implications of its truth are explained. This leads not only to a clear understanding of existence as defined by a causal connection to us, but also a specific understanding of the nature of principles and their proper philosophical application.Show less
