Philosophy from the ancient philosopher Socrates. Pretty self-explanatory. However, it is the ideas that matter more, which are below.
First problem: Socrates did not document his teachings. All that is
known about him comes from the accounts of others. Sometimes they are
mixed up with, e.g., Plato, and sometimes they contradict each other, as
human memory is imperfect.
Second problem: He was executed for being an unusual person for the
time. This is an example of how people get executed for believing things
that are contrary to common societal beliefs: lack of conformity. In most places
nowadays, at the very least, weird thoughts don't deserve the death penalty, but not
so much in ancient times!
A form of argumentative dialogue in which an individual probes a conversation partner on a topic, using questions and clarifications, until the partner is pressed to conclude on their own, or else their reasoning breaks down, and they are forced to admit ignorance. This is how debates and conversations that have the primary goal of convincing came to be. (Beware: Some people, like authority figures, really will not engage in such acts.) If a person is lonely, I also think this can be done by themselves!
Where happiness motivates all human action, directly or indirectly. For me, it depends on what the definition of happiness is, though: if it is the sensation removal of pain, I think it works, and his argument is solid. However, for him, virtue is the thing leading to happiness. As what is a virtue and what is not isn’t really clearly defined, I think this is vague.
He also thinks virtue and knowledge are linked. Since all knowledge exists in the subset of truth, virtues, which are derived from knowledge, are united as well. Unity of virtues using the example of courage: if someone knows what the relevant danger (and gain from that danger) is, they can undertake a risk.
The Socratics also introduced Q&A as a method to learn. Seemed to have been 2000 years ahead of their time, now that there are technologies with SRS.
