He gave us an insight into the Philosophical Teachings of Socrates
Socrates is regarded as one of the pioneers of Western philosophical thinking and is frequently referred to be history's first moral philosopher. Although Socrates was a well-known philosopher in his day, he left no lessons behind. Thus, Socrates is known through the works of his contemporaries, such as Antisthenes and Aristippus, as well as his pupils, including Xenophon and Plato. Most of the time, Plato used dialogue to have characters debate a topic while examining and dissecting it from multiple angles.
Early writings by Plato, referred to as "dialogues," appear to be directly derived from Socrates. The main character of these texts is primarily Plato's teacher Socrates, and the topics are frequently based on Socrates' lectures. The Apology, in which Socrates defends his convictions against accusations made by the Athenian court, is the most well-known of the Socratic Dialogues. Plato's "dialogues" are an essential resource for understanding Socrates, even though other sources present him in a different light.
