Did Plato have other people he spoke against as strongly as he did Democritus?
Plato was known for his strong opinions and criticism of other philosophers, particularly those who held views that were different from his own. Some of the other thinkers that Plato criticized in his works include:
Protagoras: Plato wrote a dialogue called "Protagoras" in which he portrays the sophist Protagoras as an arrogant and amoral teacher who is more interested in winning arguments than in seeking the truth.
Heraclitus: In the dialogue "Cratylus," Plato criticizes the pre-Socratic philosopher Heraclitus for his belief that everything is in a state of constant flux and that it is impossible to step into the same river twice.
Parmenides: Plato's dialogue "Parmenides" features a fictionalized conversation between Parmenides and a young Socrates, in which Parmenides challenges Socrates' belief in the existence of abstract, eternal forms.
Aristotle: Although Aristotle was a student of Plato, the two philosophers had significant disagreements about the nature of reality and the best way to approach philosophy. Plato criticized Aristotle's empiricist approach and his view that the material world is primary.
It's worth noting that Plato's criticisms of other philosophers were not necessarily personal attacks, but rather reflections of his own philosophical views and the intellectual debates of his time.
