Logick Quotes

I should describe mine own nature as tripartite, my interests consisting of three parallel and dissociated groups-(a) Love of the strange and fantastic. (b) Love of the abstract truth and of scientific logick. (c) Love of the ancient and the permanent. Sundry combinations of these three strains will probably account for all my odd tastes and eccentricities. (H. P. Lovecraft)

[T]he mytaphysicks and logick of the Bráhmens, comprised in their six philosophical Sástras... have never yet been accessible to Europeans; and, by the help of the Sanscrit language, we now may read the works of the Saugatas, Bauddhas, A'rhatas, Jainas, and other heterodox philosophers, whence we may gather the metaphysical tenets prevalent in China and Japan, in the eastern peninsula of India, and in many considerable nations of Tartary: there are also some valuable tracts on these branches of science in Persian and Arabick, partly copied from the Greeks, and partly comprising the doctrines of the Súfís which anciently prevailed, and still prevail in great measure over this oriental world, and which the Greeks themselves condescended to borrow from eastern sages.
