Metaphysics Midterm Study Guide
Things Said with and without Combination:
With Combination: These are full sentences, like "Man runs" or "Man wins". They connect words to share ideas.
Without Combination: These are single words or phrases, like "Man", "Ox", or "Run". They stand alone and represent ideas.
Subjects and Predication:
Key Concepts and Definitions
Things Said with and without Combination:
With Combination: These are complete sentences, like "Man runs" or "Man wins". They connect words to express full ideas.
Without Combination: These are single words or phrases, like "Man", "Ox", or "Run". They stand alone and represent separate ideas.
Subjects and Predication:
Some words can describe a subject. For example, the term "Man" tells us something about an individual person.
Other words can be part of a subject but don’t directly describe it. For instance, "Grammatical knowledge" exists in a person's mind but doesn’t point to a specific individual.
Some words can do both. For example, "Knowledge" exists in the mind and can describe different kinds of knowledge.
Lastly, some things are not described by any words, nor do they exist as part of a larger idea, like a specific person or horse.
Predication and Hierarchies:
This refers to the idea that when we attribute something to another (like describing a "Man" as an "Animal"), all properties of the first term also apply to the second.
Classification of Beings
Categories of Being:
Substance: Individual things like a man or a horse.
Quantity: How much or how many (e.g., "two feet long").
Quality: Characteristics or features (e.g., "White" or "Grammatical").
Relation: How things compare to each other (e.g., "larger" or "half").
Place: Locations (e.g., "In the Lyceum").
Time: When something occurs (e.g., "Last year").
Position: Arrangement or posture (like "sitting").
Possession: What someone has (e.g., "Wearing shoes").
Action: What someone does (e.g., "Cutting").
Affection: What happens to someone (e.g., "Being burned").
Substance and its Distinctions:
Primary Substance: These are unique individual entities that exist on their own (like a single cat or man).
Secondary Substance: These include species and groups (e.g., "Man" as a type of being, and "Animal" as a broader category).
Primary substances are the foundation of existence—everything else either describes or is connected to them.
A species is more specific than a genus; for example, "Man" gives more details than just saying "Animal".
Key Logical Principles
Predication Rules:
If something is described (said of) a subject, its name and meaning must fit that subject. If it exists within a subject, it may not always align with its definition.
Nature of Substances:
Primary substances form the base of everything else. Secondary substances reveal qualities about primary substances, highlighting their importance. No substance fits entirely within another subject, making them distinct from other characteristics.
Significance of Aristotle’s Categories
Aristotle’s framework explains how things exist and relate in our world.
The idea of substance is crucial in understanding individual beings and how their characteristics interact with each other.
The classification of substances is important in later philosophical and scientific discussions, shaping how we think about reality.
Study Questions & Answers
What distinguishes primary substances from secondary substances?
Primary substances are individual entities that exist independently (e.g., an individual man or horse). Secondary substances are the species and genera to which primary substances belong (e.g., "Man" as a species, "Animal" as a genus).
How do Aristotle’s categories help classify different aspects of reality?
Aristotle’s categories provide a framework for understanding different aspects of reality by classifying things based on their nature, such as substance, quantity, quality, relation, place, time, position, possession, action, and affection.
Why is predication important in Aristotle’s philosophy?
Predication establishes how things relate to one another logically. When one thing is predicated of another, all attributes of the predicate apply to the subject, helping to structure logical reasoning and linguistic meaning.
How does Aristotle differentiate between things "said of" and "in" a subject?
Things "said of" a subject (e.g., "Man" said of an individual man) can have both their name and definition predicated of the subject. Things "in" a subject (e.g., "White" in a body) usually do not have their definition predicated of the subject, although their name sometimes can be.
What role do species and genera play in defining substance?
Species and genera are secondary substances that provide a framework for identifying primary substances. The species is more informative than the genus because it is more specific (e.g., "Man" is more defining of an individual man than "Animal").
Key Concepts
Particulars vs. Properties
A particular is an individual entity (e.g., a table, a cat, a snooker ball).
Properties are the characteristics that a particular exhibits (e.g., brownness, hardness, four-leggedness).
The core question: Is an object just the sum of its properties, or is there something underlying them?
The Problem of Change
Objects can change their properties (e.g., a table can be painted white), yet we consider them the same entity.
This introduces the distinction between numerical sameness (being the same entity despite changes) and qualitative change (differences in properties over time).
The Substratum View
Suggests that an object has an underlying entity (substratum) that holds all its properties together.
Metaphor: A pin cushion holds pins (properties) together.
Issue: If we strip away all properties, does the substratum exist as an independent, unknowable entity?
The Bundle Theory
An alternative view where an object is nothing more than a collection (bundle) of its properties.
Advantage: Simplifies the metaphysical picture by eliminating the need for an underlying substratum.
Issue: If objects are just bundles of properties, then two objects with identical properties would collapse into one entity.
The Identity Problem
The bundle theory struggles with distinguishing between identical objects (e.g., two identical snooker balls).
Possible solutions:
Relational Properties: Each object has unique spatial or temporal properties that distinguish it.
Property Particularization: The redness of one ball is distinct from the redness of another, making each object unique.
Problem: These solutions reintroduce the concept of particularity, which the bundle theory was trying to eliminate.
Key Takeaways
Objects seem to be more than just their properties, as stripping all properties away leaves an indeterminate substratum.
The bundle theory offers a simpler approach but faces challenges in explaining how objects maintain identity and distinctness.
The concept of particularity appears to be an irreducible feature of reality.
The chapter leaves open the question: Are objects fundamentally different from their properties, or are they simply structured bundles of those properties?
Discussion Questions
How does the distinction between qualitative and numerical sameness help explain the persistence of objects through change?
Numerical sameness means an object remains the same despite changes, while qualitative change means its properties can differ over time. This distinction helps explain how an object, like a table, can be repainted but still be recognized as the same table.
What are the main challenges facing the substratum theory? Do you think it is a useful concept?
A major challenge is that if we remove all properties from an object, it's unclear whether anything remains. Some argue that a pure substratum is unknowable and unnecessary. Others find it useful to explain how objects hold properties together.
Can the bundle theory sufficiently explain why two seemingly identical objects remain distinct?
Not completely. If two objects have identical properties, bundle theory struggles to explain their difference. Solutions like spatial location or unique property instances help, but they reintroduce the idea of individual particularity.
Do you think it is possible for an object to exist without any properties? Why or why not?
Probably not. If an object has no properties, it has no way of being identified or distinguished, making its existence meaningless. Everything we recognize as an object has at least some properties.
Which theory—substratum or bundle—do you find more convincing? Why?
The bundle theory is simpler because it avoids the problem of an unknown substratum, but it struggles with identity issues. The substratum theory explains object persistence better, but it raises the problem of an unknowable entity. Preference depends on whether one values simplicity or explanatory power more.
Study Guide: Predication and Ontology in Aristotle’s Categories
1. Overview
Aristotle's Categories explores two key ideas:
Ontology: What kinds of things exist (what "is").
Predication: How we say things about what exists.
2. Aristotle’s Ten Categories (Types of Being)
Aristotle identifies ten fundamental types of things:
Substance (e.g., Socrates, a horse)
Quality (e.g., white, wise)
Quantity (e.g., five feet tall)
Relation (e.g., double, father of)
Where (e.g., in Athens)
When (e.g., yesterday)
Position (e.g., sitting)
Having (e.g., wearing shoes)
Action (e.g., running)
Passion (e.g., being burned)
3. Predication: How We Say Things About Things
A subject is what a statement is about.
A predicate is what is said about the subject.
Examples:
"Socrates is a man" (Socrates = subject, "is a man" = predicate).
"This color is white" (color = subject, "is white" = predicate).
Some things are only subjects (e.g., individual objects like "this horse"). Some things can be both subjects and predicates (e.g., "man" can describe Socrates).
Two Types of Predication
Essential (SAID OF a subject) → Describes what something is (its essence).
Example: "Socrates is a human." (Being human is part of Socrates' nature.)
Accidental (IN a subject) → Describes traits that are not essential.
Example: "Socrates is wise." (Wisdom is not what makes Socrates a human.)
4. Two Key Ontological Relations
SAID OF a subject (Essential Classification)
Example: "Man is SAID OF Socrates."
Meaning: Socrates belongs to the category "man."
Universals (general concepts) belong to this type of predication.
IN a subject (Accidental Traits)
Example: "White is IN this horse."
Meaning: The horse has the color white, but it could change.
These are dependent properties (qualities, relations, etc.).
Universals vs. Particulars
Universals (apply to many things) → Example: "Man," "White."
Particulars (specific instances) → Example: "Socrates," "This white."
5. Primary Substances: The Basic Building Blocks
Primary Substances = Individual things (e.g., Socrates, this tree).
They are not SAID OF or IN anything else.
Everything else depends on them.
Why are primary substances fundamental?
Every universal (like "human") exists only because individual humans exist.
Every property (like "white") exists only in individual substances.
6. Aristotle vs. Plato
Plato: Universals (Forms) are most real; particulars depend on them.
Aristotle: Particular substances (like Socrates) are most real; universals are just classifications.
7. Substances and Change
Substances can undergo change (e.g., Socrates can go from young to old).
Non-substances (qualities, actions, etc.) exist only in substances.
Later, Aristotle explores whether matter (rather than individual substances) is the true foundation of change.
Key Takeaways
Aristotle divides reality into ten categories of being.
Primary substances (individuals) are the most fundamental.
Predication is either essential (what something is) or accidental (a changing trait).
Aristotle’s ontology focuses on individual things, while Plato emphasizes abstract Forms
