Excerpt from The Mathematical Analysis of Logic: Being an Essay Towards a Calculus of Deductive Reasoning In presenting this Work to public tice, I deem it t irrelevant to observe, that speculations similar to those which it records have, at different periods, occupied my thoughts. In the spring of the present year my attention was directed to the question then moved between Sir W. Hamilton and Professor De Morgan; and I was induced by the interest which it inspired, to resume the almost-forgotten thread of former inquiries. It appeared to me that, although Logic might be viewed with reference to the idea of quantity, it had also ather and a deeper system of relations. If it was lawful to regard it from without, as connecting itself through the medium of Number with the intuitions of Space and Time, it was lawful also to regard it from within, as based upon facts of ather order which have their abode in the constitution of the Mind. The results of this view, and of the inquiries which it suggested, are embodied, in the following Treatise. It is t generally permitted to an Author to prescribe the mode in which his production shall be judged; but there are two conditions which I may venture to require of those who shall undertake to estimate the merits of this performance.
