Logic [PDF ebook] 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. IT is not augmenting the sciences, but disfiguring them, when their boundaries are allowed to encroach, on one another. -for which reason; and as logic is a science, wherein nothing is fully shewn and strictly proved but the formal rules of all thinking, and as we by consequence abstract in it from all objects of knowledge, as well as from their differ ence, our author has left us his logic free from every extraneous admixture of either ontological, or anthropological, ’or psychological, or metaphysi cal matter.
