"The beginning of philosophy — at least for those who take hold of it in the right way, and through the front door—is an awareness of one's own weakness and incapacity when it comes to the most important things." - Epictetus, Discourses 2.11.1
Insight: Epictetus viewed an understanding of how little one knows as the starting point of Stoicism.
 
"What is the first business of one who studies philosophy? To part with self-conceit." - Epictetus, Discourses 2.17.1
 
"There are two things that must be rooted out from human beings: presumption and lack of confidence. Presumption lies in supposing that there is nothing more that one needs... As regards presumption, that can be removed by cross-examination, and Socrates was the first to do that." - Epictetus, Discourses 2.14.8
Insight: Epictetus believed in the Socratic question and answer method for wiping out falsehoods.
 
"Since [Socrates] couldn't always have someone at his side to subject his judgments to examination, or to be cross- examined by him in turn, he used to subject himself to examination, and test himself out, and was always trying out the practical application of some specific preconception." - Epictetus, Discourses 2.1.32
Insight: We can apply the habit of Socratic questioning internally.
 
"Is health good, and disease evil?” No, you can do better than that. “What then?” To use health well is good, to use it badly is evil." - Epictetus, Discourses 30.20.4
Insight: Our circumstances in themselves cannot be judged, rather our actions given our circumstances.
 
"Men are disturbed not by the things that happen but by their opinions about those things." - Epictetus, Enchiridion 5
Insight: Stoicism starts by suggesting that what might be considered problems can often be reinterpreted as problems in your thinking.
