In the 89th letter to Lucilius Seneca divides philosophy into three parts, namely ethics, physics, and logic. As philosophy in general he also divides its ethical parts into three parts: the first one has to do with value judgments, the second with impulses, and the third with actions. But instead of characterizing each of these parts and giving an overview of their contents he rather describes an ideal action: first, one makes a correct value judgment, then, one initiates a regulated (...) and ordered impulse, and finally, one brings this impulse into harmony with one’s external action by paying attention to the circumstances under which one intends to act. If each of these action moments has the mentioned character, one is consistent with oneself—an important step towards reaching full self-consistency, i.e., virtue. If those moments do not have the mentioned character, as for example in a passion, one cannot be consistent with oneself. As a result, one diverges from the goal of full self-consistency and thus from virtue. The thesis of my book takes up the parallel Seneca is drawing between ethics and its parts on the one hand and an action and its moments on the other hand. I argue that his ethics is based on an action theory that has as its main moments a judgment, an impulse and an external action. Within this theoretical framework, Seneca gives an answer to the question of what one should do in order to reach full self-consistency, i.e., virtue, which for a Stoic like him is a necessary and sufficient condition for happiness. My book, correspondingly, has two major parts: first, I am working out Seneca’s action theory and its philosophical origins, then, I am concerned with his ethics. In the first main chapter, I further argue that his action theory stems for the most part from the early Stoics, but that unlike them he has a concept of will. This concept, as I want to show in the second part, plays an important role in his ethics, too. (shrink)

Cynicism is a unique philosophy. You could even say that they took their principles a little too far, perhaps. Diogenes' core idea was that Man should live in accordance with nature, as simply as possible. He along with his students were missionaries of a sort, traveling city-to-city preaching about the life of simplicity. To Diogenes, material things like money and lavish accessories corrupted nature. Not only did he despise concrete things, but he also disapproved of social conventions. Like every philosopher (...) in the Hellenistic period, Diogenes believed that virtue was the highest good. Virtue was the rejection of desires and the pursuit of goods earned by the individual, according to Diogenes. What he meant by goods earned by the individual was that things granted by other people and nature happen purely by chance. Diogenes said that everything we own should come from ourselves: confidence, happiness, et cetera. Diogenes said that everything we own should come from ourselves: confidence, happiness, et cetera. Two of the key principles of Cynicism were freedom (eleutheria, ελευθερια) and free speech (parrhesia, παρρησια). To be a Cynic, you must be free from society's and life's constraints and you must also speak without fear. Desires of wealth and reputation were unnatural and made us less human, property and social classes dehumanized us, and conventional, man-made norms limited our freedom. (shrink)
