Study Notes
Antisthenes and the Dilemma
- Antisthenes presents a dilemma: a proposition is either a tautology or self-contradictory.
- Example: Arguing that "a cloud is white" equates to saying a cloud is not itself, resulting in a contradiction.
Tree of Porphyry
- An arrangement depicting basic genera and species in the universe.
- Illustrates the inverse relationship between extension (number of members) and comprehension (number of properties).
- Moving down the tree increases comprehension but decreases extension.
- Acts as a metaphysical map, guiding understanding of existence.
Predicables
- Predicables describe the relationship between subjects and predicates in propositions.
- Examples of propositions include statements about justice and human nature.
- Emphasizes the importance of understanding essence in philosophy and logic.
Essence versus Scientific Definitions
- The human mind inherently questions essence, as shown through a child's inquisitive nature.
- Commonsense knowledge of essences serves everyday conversation but lacks scientific clarity.
- Modern science avoids intuitively derived definitions, focusing instead on observable actions.
Confusion of Concepts in Logic
- Modern logic struggles with the question of essence, which was central to ancient thought.
- The law of non-contradiction supports stating "S is S" without asserting "S is P."
Clarification on Accidents, Genus, and Species
- "Accident" as a term applies to categories except substance; it contrasts with predicables, which relate to subject-predicate relationships.
- Genus and species rely on the essence of subjects and inform classification in propositions.
- Aristotelian logic defines genus and species in relation to intrinsic properties rather than subjective classifications.
Terms and Their Usages
- Terms can be univocal (one meaning), equivocal (multiple unrelated meanings), or analogical (partly related meanings).
- Examples include usage of "good" which varies in context but retains some commonality across applications.
Predicables vs. Categories
- Predicables classify predicates based on their relation to subjects.
- Five predicables approach the essence of the subject more closely than others.
- Symbolic logic neglects predicables because they assume intrinsic nature, a concept deemed forbidden.
Types of Predicables
- The species articulates the essence (e.g., "man is a rational animal").
- The genus denotes the general nature (e.g., "animal" as the genus for "man").
- Forgetting essence complicates the understanding of relationships and classifications in both logic and philosophy.
