Reason is the guiding principle of Stoic philosophy from "summary" of The Stoic Life by Tad Brennan
The Stoics believed that reason is the guiding principle of their philosophy. This means that they viewed reason as the key to living a good life. According to the Stoics, reason is what allows us to understand the world around us and to make rational decisions. It is through reason that we are able to distinguish between what is within our control and what is not. By using reason to focus on what is within our control, the Stoics believed that we could achieve a sense of inner peace and tranquility. This is because when we focus on things that are within our control, we are not troubled by external events that are outside of our control. Instead, we are able to maintain a sense of emotional equilibrium and not be swayed by our desires or fears. The Stoics also believed that reason is what allows us to live in accordance with nature. By using reason to understand the natural order of the world, we are able to see that everything is interconnected and that we are all part of a larger whole. This understanding helps us to be more compassionate towards others and to live in harmony with the world around us.- Reason is what allows us to live a virtuous and fulfilling life according to Stoic philosophy. By using reason to guide our actions and decisions, we are able to achieve a sense of inner peace, live in harmony with nature, and cultivate virtues such as wisdom, courage, and justice. Ultimately, reason is what enables us to live a good life and to flourish as human beings.
