Socrates

Before Socrates, in Athens there was only sophists they were people who were paid for teaching. Socrates enter to this sophists class and start to question about everything. In a couple of classes Socrates became from student to teacher. After this he started to give classes in the streets and were free, because he thought eisdom shouldn't be charged. This is when he created the term Philosopher, that is the one who teaches not in exchange of money, only for love to knowledge.

Socrates focused in two main things: society and argumentation. he was the master of argumentation.
