Existential Graphs carry the logical analysis of reasoning the furthest point possible. We investigate the analytic virtues of the Alpha part. We examine proposal that illation is the primitive relation defend the view that this idea constitutes the fundamental motive of philosophy of notation both in algebraical and graphical logic. We explain how Peirce arrived at logical constants that represent both scope and truth function in his algebras and graphs. We show that Shin's (2002) argument for multiple readings of Alpha graphs is circular.
