METAPHYSICS I: UNIVERSALS

Philosophy
Philosophy
• Universals are entities that exist beyond space and time; physical objects and
qualities resemble universals to some extent (such as a person is tall because
he/she partakes of the tallness more than shortness)
• Particulars (individuals) are objects or events within space and time which manifest
characteristics of one or more universals (such as the tall person is a particular or
individual)
• A particular can admit contrary universals (such as a person can possess tallness
and shortness in different quantities); only universals remain fixed and unchanging
REALISM
• Universals have the only true reality, or possess greater reality than particulars
• Reality would continue as it is, even if there were no human subjects to perceive it,
because it has an essence independent of human perception
• Universals depend on human perception to exist
• They do not exist beyond the time they are perceived or conceptualized
DEFENSES OF REALISM
CONCEPTUALISM
• Universals lack a real existence; they are merely abstract terms or names
• As opposed to Realism, particulars exist prior to universals
• If there were no language for humans to conceive of universals, then universals
would not exist
NOMINALISM
REALISM OF NATURES
REALISM OF THINGS
Medieval Each object in the real world participates in the nature of ideal
Realism of itself; that nature may be absolute, specific, or generic
Platonic Each object or quality in the real world owes its existence to
Realism resemblance to, or participation in, ideal form of itself; forms
exist beyond realm of senses (eternal and immutable)
Anti-realism Refusal to accept unverifiable statements (that is, truths that
cannot be verified)
Common Sense All objects outside the mind exist in a concrete sense Realism
• It is given because it conforms to common experience
Neo-realism Objects external to the mind are concrete entities and do not
depend on the mind in order to exist
Critical Realism Mind apprehends external objects as they are duplicated in the
mind • Object is inaccessible; only its conceptual counterpart
can be mentally perceived
Abstracta A term (such as tallness, shortness) referring to a quality that is
considered separately from the particular object that exhibits it
• The existence of abstracta in language suggests that such
qualities exist separately as universals
Predication Logical propositions take the form of a subject and predicate
(such as in the proposition Susan is tall,” Susan is the subject
and is tall is the predicate) The predicates of true propositions
would be meaningless if they did not refer to universals
Resemblance Universals account for the resemblance of particulars
• The form “Susan resembles Jennifer” is logically incomplete; it
requires existence of some universal to determine exactly how
two particulars, Susan and Jennifer, resemble each other
Note: Third type of realism states that each object in real world is derived from a
law or model that exists abstractly in natural science
METAPHYSICS II:
PARTICULARS
• Particulars possess essences (something that
makes an object what it is, without which
that object would cease to be itself)
• Distinguishes between essential and
accidental traits of a particular
Counter-Example: A syllogistic scenario that
contradicts essentialism; subjects it to de re
reading
S1: Atomic scientists are necessarily scientists,
but are not necessarily Spanish.
S2: Spanish women are necessarily Spanish, but
not necessarily scientists
S3: Maria is an atomic scientist and Spanish.
Therefore, S4: Maria is necessarily a scientist but
not necessarily Spanish, and necessarily Spanish
but not necessarily a scientist.
S4 forces false conclusion that Maria does not
exist because her description (S3) entails
contradiction
• This objection is sound if it is limited to de re
analysis; contradiction does not occur on de
dicto reading
ESSENTIALISM
• Each substance is distinct because of bare
particulars that determine the main
characteristics of the substance
• Bare particulars are those parts of a particular
without which it would cease to be what it is
BARE PARTICULARS
• Each particular is nothing more than a bundle
of different kinds of items, or different
properties that constitute it
• Each particular is distinct because it is logically
impossible for two or more objects to possess
identical properties
BUNDLE THEORY
• Any theory that posits the existence of two
mutually exclusive substances or conditions
• Most types of dualism concentrate on the
mind-body split
Examples: How can humans reconcile mental
and physical stimuli? If only physical
substances exist (a claim of Materialism), then
do thoughts and sensations not exist?

there can substances, rather than substances be only one valid morality in the world, themselves; existence of physical matter is which is eternal and superhuman • Certain denied • God is responsible for presence of religious moral systems are absolutist ideas in mind; we receive messages from God, which are natural laws (physical realm) Conventionalist Ethical qualities are true within a given Cartesian Dualism Human reality consists of a dualism Ethical culture or society • According to the between living in a world of physical Relativism diversity thesis, morality varies among different cultures, and no moral views apply objects and thinking things that exist in a to all cultures • According to the purely conceptual form • Human dependency thesis, each morality is experience entails interaction between the justified through its acceptance within its cognitive and physical worlds • God is culture responsible for this interaction between the mental and physical realms • Thought is Moral Realism Ethical qualities are objectively true, and unextended (non-spatial);

governed by natural (scientific) laws • Justification of moral codes follows some they postulate that mental and physical system of scientific justification • The universe states constitute a unity • Schelling sees is one; all objects in it and all aspects of it mental and physical states as part of the are equally accessible to scientific study same whole which he calls the Absolute • The real and ideal exist as opposites Non-cognitivism Ethical knowledge is impossible; ethical within the absolute, with the ideal as statements are descriptive expressions of positive value towards which everything subject’s attitude to some object or tends • Spinoza views both mental and condition • Neither empirical nor ideal physical states as parts of a structure that frame of reference exists for ethics; only consists of the whole world • Complete individual’s subjective emotions dictate structure is substance, nature, or God (all moral judgments parts are necessary to whole); Spinoza Objectivism/ Qualifies moral realism by stating that claims that entire world is a unity Ethical objective ethical qualities are built by human Kantian Dualism Reality consists of a dualism between the Constructivism choice; ethical qualities exist only through phenomenal world (the world as it the agreed impartial choice of all people appears to us) and the noumenal world Rationalism Ideal view of ethics, in which morality is a (the world as it is in itself) • Humans can purely conceptual science based on reason have no knowledge of the noumenal realm • Rationalism assumes moral judgments are • Kant defines noumenon as the object of m a non-sensuous intuition, but states that a priori and independent of the natural o world • Ethical justification follows only sensuous intuitions can exist; mathematical model of assessment c therefore, even for Kant, noumenon is . described as merely x Materialism Hobbes denies existence of mental reality; s only physical matter • Interaction of mind t and body is not a question;
