Simmias of Thebes appears as a main discussion partner in a dialogue from the man who founded what?
Plato Plato ( ; Greek: Πλάτων "Plátōn", ] in Classical Attic; 428/427 or 424/423 – 348/347 BC) was a philosopher in Classical Greece and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, especially the Western tradition. Unlike nearly all of his philosophical contemporaries, Plato's entire work is believed to have survived intact for over 2,400 years. Others believe that the oldest extant manuscript dates to around AD 895, 1100 years after Plato's death. This makes it difficult to know exactly what Plato wrote.
Against the Sophists Against the Sophists is among the few Isocratic speeches that have survived from Ancient Greece. This polemical text was Isocrates' attempt to define his educational doctrine and to separate himself from the multitudes of other teachers of rhetoric. Isocrates was a sophist, an identity which carried the same level of negative connotation as it does now. Many of the sophistic educators were characterized as deceitful because they were more concerned with making a profit from teaching persuasive trickery than of producing quality orators that would promote Athenian democracy. Isocrates was more concerned with the latter of these objectives and sought to separate himself from these less reputable sophistic teachers. After opening his school around 393 or 392 BC, Isocrates wrote "Against the Sophists" to clearly distinguish his teaching methods from the commonly held view of sophistic education.
