Gradually, he eliminated simpler logical works and added monographs on logic by Boethius, an early 6th-century Roman philosopher.
Historical precedents for the pedagogical and research interests that characterize informal logic include Aristotle's rhetorical and logical works, which have been a touchstone for much discussion.
For all his deserved reputation, his logical views are sometimes derivative[11] and occasionally very idiosyncratic.[12] Ockham's main logical writings consist of a series of commentaries (or "expositions") on Aristotle's and Porphyry's own logical works, plus his own Summa of Logic, his major work in the field.
Aristotle's logical works contain the earliest formal study of logic that we have.
However, it should be noted that: (1) these arguments draw on Aristotle's views about logic to a greater extent than any treatise outside the logical works themselves; (2) in the logical works, the principle of non-contradiction is one of Aristotle's favorite illustrations of the "common principles" (koinai archai) that underlie the art of dialectic.
In the monumental if rarely creative volumes of the Greek commentators on Aristotle's logical works we find elements of Stoic and later Peripatetic logic; the same holds for the Latin logical writings of Apuleius (2nd c. CE) and Boethius (6th c. CE), which pave the way for the thus supplemented Aristotelian logic to enter the medieval era.
Although placed by long tradition among his logical works (see the discussion in the entry on Aristotle's logic), due to its analysis of the terms that make up the propositions out of which deductive inferences are constructed, the Categories begins with a strikingly general and exhaustive account of the things there are (ta onta)—beings.
His logical works are not extant.
These characters, and the rest of the programmers, are the least mystical people imaginable, but their severely logical work invokes great mysteries.
This introduction soon became an integral part of the Organon (the logical works of Aristotle) and thus acquired undeserved Aristotelian authority in all schools for more than 1,500 years.
Some spintronic devices may be able to do more logical work with a given number of components than traditional chips can manage.
