Ibn Rushd speaks only of &#8220;the philosopher&#8221;, but the priests spread the lie that this &#8220;philosopher&#8221; was &#8220;Aristotle&#8221;, an early Greek hence &#8220;friend of the church&#8221;, like the non-existent Euclid. This lie was essential to portray &#8220;Aristotle&#8221; as theologically correct and enable the church to adopt reason.\u00a0 (Islamic thinkers routinely conflated &#8220;Neoplatonic&#8221; or sufi philosophers like Plotinus, and Proclus with &#8220;Arasto&#8221;, and valued the &#8220;theology of Aristotle&#8221; (or &#8220;paganism&#8221;), contrary to church dogmas.)<\/div>\n<div class=\"D_F en_0\"><\/div>\n<div class=\"D_F en_0\">At any rate, Christian priests spread the falsehood that logic began with Aristotle (the way they spread the falsehood that math began with Euclid). To highlight the confusion involved, I have separated the fabricated 12th c. &#8220;Aristotle of Toledo&#8221; from the historical &#8220;Aristotle of Stagira&#8221;, Alexander&#8217;s tutor and possible recipient of the books that Alexander looted from Persia and Egypt, and got translated into Greek.The story that the Arabic books at Toledo originated from early Greece is a church and racist lie for which there is no evidence.<\/div>\n<div class=\"D_F en_0\"><\/div>\n<div class=\"D_F en_0\">For any knowledge to develop, the social conditions must be there, and the social conditions provide evidence to the contrary. Indeed, there was no tradition among early Greeks of any long debates, so no need for anyone to develop a syllogism. Aristotle, like Socrates, risked being condemned to death: the usual early Greek way of settling an argument. In contrast, in India there were fierce debates between Buddhist and Jains, or Buddhists and Naiyayikas etc. In India, people debated with each other to establish truth, and did not simply kill their opponents in the manner of early Greeks and the medieval church. Because of these social conditions, all Indian schools developed elaborate syllogisms to put their point across effectively.<\/div>\n<div class=\"D_F en_0\">Now, &#8220;Aristotle of Toledo&#8221;, i.e., Arabic literature in the 12th c., comes long after the spread of Indian knowledge to Arabs, in the 8th c. Hence, I have repeatedly pointed out <a href=\"http:\/\/ckraju.net\/blog\/?p=190\">possible Indian inputs to that knowledge in Arabic texts<\/a> wildly attributed to early Greeks by dishonest church and racist historians (e.g. in astronomy and &#8220;trigonometry&#8221;).

The gap between traditional syllogistics  and the mathematical or philosophical logic of the early 20th century  looked too wide. Some authors simply divided the history of their  discipline into two areas: the old and the new logic.<\/div>\n<div>In  recent decades, however, researchers have often shown that there are old  logics with enormous potential: numerous modern systems in the field of  visual reasoning are based on the Aristotelian square of opposition, on  the arbor porphyriana or on Euler&#8217;s logic diagrams. In Arabic logic the  consequence relations show alternatives to modern approaches. Today,  Indian logic is often associated with paraconsistency and dialetheism,  and in the field of natural language processing, medieval logicians are  increasingly used to circumvent the artificiality of many modern  systems. In modal logic, Aristotelian and scholastic logics are again  increasingly discussed. And in early modern period unique propositional  calculi and extended syllogistics are discovered frequently, which pose  challenges to interpretation. All this proves that `the old logic\u2019 is  still full of new ideas and that current research has to rethink how to  rewrite the history of logic in modern terms.<\/div>\n<div>*******************************************************<\/div>\n<div>CALL FOR PAPERS.<\/div>\n<div>Papers  on all aspects of research in the history of logic and its modern  interpretation are welcome.
