This paper argues firstly that the argument of Hegel's Phenomenology of Spirit is necessary for the justification of the beginning of his logical project, and secondly that Hegel's attempt to secure the beginning of his Science of Logic by relying upon the argument of the Phenomenology fails. I argue firstly that the position taken up at the beginning of Hegel's Logic is constructed in such a fashion that it relies upon the argument of the Phenomenology to justify it. I then (...) offer some support for the view of the relationship between the two texts defended by Maker in order to see how the two might be thought to be compatible. Finally, in the longest part of the paper, I offer a number of reasons for thinking that attempts to render the two compatible in this fashion fail. I therefore conclude that, as it stands, the beginning of Hegel's Logic is not secured against objection in the way that Hegel wants it to be. (shrink)
