Introducing Plato
D. Robinson & J. Groves
The Sophists sold their wisdom for profit. They treated philosophy as a self-help method to earn political position.
Plato & Socrates were hostile to the Sophists for two reasons:
1. The Sophists debased philosophy
2. The Sophists sold their teaching to whoever could pay, not just the Aristocracy
Sophists were on a sliding scale, but preached cultural and ethical relativism and ethical skepticism. The worst held ethical nihilism as a viewpoint.
Protagoras (490-420 BC)
- Agnostic
- Ethical relativist
While Protagoras was a relativist and Sophist he did garner some respect from Plato and Socrates, which is more than the cynical Callicles in the Gorgias got.
The Meno:
Concludes that virtue cannot be taught, it must be recalled.
"For Plato, knowledge is something we are already born with, and so 'learning' is simply forcing this knowledge to resurface into our conscious minds" (Robinson, 44).
Learning is anamnesis - recalling something imparted from the divine to the pre-existant souls of men.
The Republic:
Thrasymachus argues that society and the state are artificial constructs to limit the natural state of men.
Thrasymachus' views on morality predicted the views of Nietzsche and Marx.
Glaucon has a very negative view of humanity and posits a psychological egoist viewpoint. Humans are vicious, predatory beasts. Thomas Hobbes adopted this view and advocated strong governments to enforce morality.
Plato chooses not to argue against this as "psychological egoist explanations of all human behavior usually tend to be self-confirming and difficult to refute (Robinson, 60).
