"  Systematic concept of logic "
Biography    
      Aristotle was born in Stagirus,or Stagira,or Stageirus,on the Chalcidice peninsula of northern greece. His father was Nicomachus, a medical doctor while his mother was named Phaestis.Nicomachus was certainly living in Chalcidice when Aristotle was born and he had probably been born in that region. Aristotle's mother was Phaestis,came from Chalcis in Euboea and her family owned property there. When Aristotle was about ten  years old his father died. This certainly mean that he can't follow his father's profession of doctor and since his mother seems also have to have died young. Aristotle have his own guardian , Proxenus of Atarneus who was his uncle . Aristotle famous philosophy was the systematic concept  of logic .
Philosophy
   One of the main focuses of Aristotle's phiosophy  of reasoning that would  allow man to learn every conceivable thing about reality. The initial process involved describing objects based on their characteristics, state of being and actions.In his philosopical treatises. Aristotle also discussed how man might next obtain information about objects through deduction and inference. To Aristotle, a deduction was a reasonable argument in which " when certain things are laid down, something else follows out of necessity in virtue of their being so." His theory of deduction is the basis of what philosophers now call a syllogism, a logical argument where the conclusion is inferred from two or more other premises of a certain form. In his book Prior Analytics, Aristotle explains the syllogism as" a discourse in which certain things having been supposed,something different from the things supposed results of necessity because this things are so." Aristotle defined the main components of reasoning in terms of inclusive and exclusive relationships. These sort of relationships were visually grafted in the future through the use of Venn diagrams. Aristotle's philosophy not only provided man with a system of reasoning,but also touched upon ethics. In Nichomachean Ethics, he prescribed a moral code of conduct for what he called" good living". He asserted that good living to some degree defied the more restrictive laws of logic, since the real world poses circumtances that can present a conflict of personal values. That said, it was up to the individual to reasons cautiously while developing his or her own judgement.
Analysis
    One of the main focuses of aristotle's philosophy was his systematic concept of logic.Aristole's objective was to come up with a universal process of reasoning that would allow man to learn every conceivable thing about reality   A lecturer in Athens, Aristotle studied and discussed the systematic understanding of logic, physics,astronomy,meteorology,
zoology,metaphysics,theology, psychology,politics,economics,
ethics,rhetoric,and poetics. While Aristotle's contributions in each  subject were considerable for the time,his major contribution was to the overall study and teaching of such subjects in a systematic way, many of which had never been considered before. Two areas which he advanced were physics and astronomy. He made every interesting discussion of the topics of matter, change movement,space, position, and time as well as studying comets.
Conclusion
     I conclude that one of the main focuses of Aristotle's philosophy was his systematic concept of logic. Aristotle's objective was to come up with a universal process of reasoning that would allow man to learn every conceivable thing about reality. Aristotle ia a philosopher who want people to think very logically.The logic of Aristotle is primarily a study of the syllogism. Syllogism means deductive reasoning.
