What we today call "Aristotelian તર્કશાસ્ત્ર", એરિસ્ટોટલ himself would have labeled "analytics". The term "logic" he reserved to mean "dialectics". Most of એરિસ્ટોટલ 's work is probably not in its original form, since it was most likely edited by students and later lecturers. The logical works of એરિસ્ટોટલ were compiled into six books in about the early 1st century AD:

The order of the books (or the teachings from which they are composed) is not certain, but this list was derived from analysis of એરિસ્ટોટલ's writings. It goes from the basics, the analysis of simple terms in the Categories, to the study of more complex forms, namely, syllogisms (in the Analytics) and dialectics (in the Topics and Sophistical Refutations). There is one volume of એરિસ્ટોટલ's concerning logic not found in the "Organon", namely the fourth book of "Metaphysics.".
