Metaphysics Book VI and Book VII
Introduction to Metaphysics
Focus on seeking principles and causes of being.
Different sciences have their own principles, focusing on specific beings or genera, but do not address the essence of being generally.
Understanding 'Being'
Not all sciences address existence (whether something is) as part of their inquiry.
Natural sciences focus on substance and movement; they differ from practical and productive sciences.
Natural Science: Concerned with substances that have internal principles of movement and rest.
Theoretical Sciences
Divided into three categories:
Physics: Deals with movable substances.
Mathematics: Focuses on immovable entities, sometimes separate from matter.
Theology: The study of eternal, immovable, and separate existence.
Theoretical science is valued higher than practical or productive sciences, and theology is regarded as the highest form.
The Meaning of Being
The term 'being' carries multiple meanings:
Accidental vs. essential being.
Consideration of potential vs. actual being.
Accidental Being: Lacks scientific treatment; seen as a mere name without necessary attributes.
Example: Building a house has many unintended attributes that are not within the builder's control.
Characteristics of Accidental Being
Accidental beings are neither consistent nor constant (not always nor mostly).
Examples of accidental events:
Weather conditions inconsistent with typical patterns (e.g., winter during hot months).
Attributes, like a person's color, might not define their essence.
Causation in Being
Distinction between causes that are necessary vs. those that are accidental.
Events occur based on conditions that lead to outcomes (chain of events).
Necessity of a first cause that is neither accident nor dependent on other factors.
Substance and Its Categories
Inquiry into what constitutes substance, differentiated between:
Essence: The nature of something as it is.
Universal and Genus: Common traits among classes of things.
Substratum: That which underlies all predicates (the foundation).
Discussion on how matter, shape, and combinations define substance.
Complexity of Substance
Philosophical debate on whether only physical objects are substances or if other forms (like mathematical entities) also qualify.
Different philosophical traditions argue for various aspects of substance:
Plato's Forms versus material entities.
The potential existence of substances beyond the sensible world.
Essential Nature of Substance
Essence: What it means for something to be what it is.
Clarified that essence cannot simply be a combination of attributes (e.g., being white or tall).
The essence is that which is essential to a thing's nature, not dependent on additional descriptors.
Conclusion
Further exploration required on the concepts of essence and predicates in defining substance.
Aim to clarify how predicates imply substance and lead us to understand the nature of existence.
