Concise Summary of Hobbes's Psychological Theory and Ethical Concepts

Two types of human motion:
- Vital motion: Automatic processes like breathing and digestion.
- Animal motion (voluntary motion): Movements initiated by thought.
Endeavor: Initial, often imperceptible internal motions preceding visible actions like walking or speaking.
Appetite and Aversion:
- Appetite: An endeavor towards something, typically equated with desire.
- Aversion: An endeavor away from something, often associated with hate.
Nature of Evaluations:
- Good: Whatever fulfills an appetite.
- Evil: What causes aversion.

In a presocial state, desires and aversions primarily serve self-preservation, leading to Hobbes's concept of felicity (happiness).
Desire for Power: Humans have an inherent and continual desire for power, equated with self-preservation.
War of All Against All: Lack of societal structure leads to a continual state of conflict due to competition, diffidence, and desire for glory.

Good and evil are subjective: defined by personal desires and contexts, not absolute values.
Society originates from self-interest and fear rather than altruism.
