Logic (from the Ancient Greek: λογική, logike) is the branch of philosophy concerned with the use and study of valid reasoning. The study of logic also features prominently in mathematics and computer science.
Logic was studied in several ancient civilizations, including Greece, India, and China. In the West, logic was established as a formal discipline by Aristotle, who gave it a fundamental place in philosophy. The study of logic was part of the classical trivium, which also included grammar and rhetoric. Logic was further extended by Al-Farabi who categorized it into two separate groups (idea and proof). Later, Avicenna revived the study of logic and developed relationship between temporalis and the implication. In the East, logic was developed by Hindus, Buddhists and Jains.
Logic is often divided into three parts: inductive reasoning, abductive reasoning, and deductive reasoning.
The concept of logical form is central to logic. The validity of an argument is determined by its logical form, not by its content. Traditional Aristotelian syllogistic logic and modern symbolic logic are examples of formal logic.
Roger Hodgson (Supertramp lead singer & songwriter) wrote this hit when he was still in his teens, before he even met Rick and co-founded Supertramp. This classic is just as relevant today as it was when it was released. Roger won the Ivor Novello Award from The British Academy of Composers and Songwriters for The Logical Song being named the best song both musically and lyrically. It also has the distinction of becoming one of the most quoted lyrics in schools. Roger's World Tour is getting rave reviews, Roger performs his songs in a variety of formats so you can see him at an acoustic show, band show or orchestra. I love them all. http://www.rogerhodgson.com / http://www.facebook.com/rogerhodgson. LYRICS PAGE ~ http://www.rogerhodgson.com/lyrics/lyrics.html 2016 World Tour Nov 7 Q...
