it’s interesting how far modern usage of some philosophy-related words winds up from the original meaning. e.g.:
Cynicism (Ancient Greek: κυνισμός) is a school of thought of ancient Greek philosophy as practiced by the Cynics (Ancient Greek: Κυνικοί; Latin: Cynici ). For the Cynics, the purpose of life is to live in virtue, in agreement with nature. As reasoning creatures, people can gain happiness by rigorous training and by living in a way which is natural for themselves, rejecting all conventional desires for wealth, power, and fame, and even flouting conventions openly and derisively in public. Instead, they were to lead a simple life free from all possessions.
- an inclination to believe that people are motivated purely by self-interest; skepticism.
