Lesson Plan
"The point of philosophy is to start with something so simple as to seem not worth stating, and to end with something so paradoxical that no one will believe it."
Bertrand Russell
(From
The Philosophy of Logical Atomism, Lecture II)
What is "philosophy"?
It
is the branch of intellectual studies concerned with questions of how one
should live (ethics); what sorts of things exist and what are their essential
natures (metaphysics); what counts as genuine knowledge (epistemology); and
what are the correct principles of reasoning (logic). The word itself is of
Greek origin: filosofiøa (philosophÌa), a compound of filoþ (phÌlos: friend, or lover) and sofiøa (sophÌa: wisdom).
It is very
difficult to come up with a single expanded definition of what the field of
philosophy really concerns itself with. Most philosophers agree in general
principle that it is a method or tool of investigation, instead of a set list
or canon of beliefs and theories. Key to the understanding of this field is
that its investigations are based upon pure reason, with no unexamined
assumptions and no reliance on unexamined faith or pure analogy. Within the
field of philosophy many hold very different conclusions about the nature of
reason, and even what is included among the subject matter of philosophy
itself. One major school of thought holds that it examines the process of
inquiry itself; or in other words, "thinks about thinking." The other major
school of thought holds that there are essentially philosophical propositions
which it is the task of philosophy to prove, such as the nature of reality or
the simple validity of truth.
Yes, this is
quite heavy material!
What
is included in the study of philosophy?
There
are four major divisions of the study of philosophy:
Metaphysics refers to the branch of
philosophy that attempts to understand the fundamental nature of all reality,
whether visible or invisible. It seeks a description so basic, so essentially
simple, so all-inclusive that it applies to everything, whether divine or human
or anything else. It attempts to tell what anything must be like in order to be
at all.
This was first
studied systematically by Aristotle, though he did not use that term. He calls
it "first philosophy" (or sometimes just "wisdom"), and
says it is the subject that deals with "first causes and the principles of
things". The modern meaning of the term is any inquiry dealing with the
ultimate nature of what exists. Within metaphysics, ontology is the inquiry
into the meaning of existence itself, sometimes seeking to specify what general
types of things exist (though sometimes the term is taken to be equivalent to
metaphysics). The philosophy of mind is a part of metaphysics.
Epistemology is concerned with the nature
and scope of knowledge, and whether knowledge is possible. It also attempts to
answer a basic question: what distinguishes true (adequate) knowledge from
false (inadequate) knowledge? Among its central concerns has been the challenge
posed by skepticism: the idea that all our beliefs and thoughts may be somehow
illusory or mistaken.
Defined
narrowly, epistemology is the study of knowledge and justified belief. As the
study of knowledge, epistemology is concerned with the following questions:
What are the necessary and sufficient conditions of knowledge? What are its
sources? What is its structure, and what are its limits? As the study of
justified belief, epistemology aims to answer questions such as: How we are to
understand the concept of justification? What makes justified beliefs
justified? Is justification internal or external to one's own mind? Understood
more broadly, epistemology is about issues having to do with the creation and
dissemination of knowledge in particular areas of inquiry. This article will
provide a systematic overview of the problems that the questions above raise
and focus in some depth on issues relating to the structure and the limits of
knowledge and justification.
Ethics, or 'moral philosophy', is
concerned with questions of how agents ought to act. Plato's early dialogues
constitute a search for definitions of virtue. Metaethics is the study of
whether ethical value judgments can be objective at all. Ethics can also be
conducted within a religious context.
The field of
ethics involves systematizing, defending, and recommending concepts of right
and wrong behavior. Philosophers today usually divide ethical theories into
three general subject areas: metaethics, normative ethics, and applied ethics.
Metaethics investigates where our ethical principles come from, and what they
mean. Are they merely social inventions? Do they involve more than expressions
of our individual emotions? Metaethical answers to these questions focus on the
issues of universal truths, the will of God, the role of reason in ethical
judgments, and the meaning of ethical terms themselves. Normative ethics takes
on a more practical task, which is to arrive at moral standards that regulate
right and wrong conduct. This may involve articulating the good habits that we
should acquire, the duties that we should follow, or the consequences of our
behavior on others. Finally, applied ethics involves examining specific
controversial issues, such as abortion, infanticide, animal rights,
environmental concerns, homosexuality, capital punishment, or nuclear war. By
using the conceptual tools of metaethics and normative ethics, discussions in
applied ethics try to resolve these controversial issues. The lines of
distinction between metaethics, normative ethics, and applied ethics are often
blurry. For example, the issue of abortion is an applied ethical topic since it
involves a specific type of controversial behavior. But it also depends on more
general normative principles, such as the right of self-rule and the right to
life, which are litmus tests for determining the morality of that procedure.
The issue also rests on metaethical issues such as, "where do rights come
from?" and "what kind of beings have rights?"
Logic has two broad divisions: mathematical
logic (formal symbolic logic) and what is now called philosophical logic, the
logic of language. It is concerned with
characterizing notions like inference, rational thought, truth, and contents of
thoughts, in the most fundamental ways possible, and trying to model them using
modern formal logic.
The notions in
question include:
-
Reference: a relation between objects in which one
object designates, or acts as a means by which to connect to or link to,
another object
-
Predication: a high level pursuit that defines which
statements of first order logic are provable
-
Identity: is whatever makes an entity definable
and recognizable, in terms of possessing a set of qualities or characteristics
that distinguish it from entities of a different type. Or, in layman's terms,
identity is whatever makes something the same or different.
-
Truth: There are differing claims on such
questions as what constitutes truth; how to define and identify truth; what
roles do revealed and acquired knowledge play; and whether truth is subjective,
relative, objective, or absolute.
-
Negation: an operation on logical values, for
example, the logical value of a proposition, that sends true to false and false
to true. Intuitively, the negation of a proposition holds exactly when that
proposition does not hold. In grammar, not is an adverb which acts as a
coordinating conjunction.
-
Quantification: has several meanings, general and
specific. Primarily it covers all those acts which quantify observations and
experiences by converting them into numbers through counting and measuring.
-
Existence: a branch of philosophy known as
ontology. Many questions arise concerning existence. Is what we experience and
observe all there is to existence? Do abstract ideas, such as virtue, exist? Is
existence orderly and knowable or chaotic and unknowable? Does there exist an
external reality that is completely ontologically independent of our conceptual
schemes, linguistic practices, and beliefs?
-
Necessity: a complex set of concepts like
possibility, existence, and contradictions
-
Definition: a statement of the meaning of a term,
word or phrase.
-
Entailment: (or logical implication) is a relation
between sets of formulae such that, if A and B are sets of formulae of a formal
language, then A entails B if and only if every model (or interpretation) that
makes all the members of A true, makes at least one of the members of B true.
Philosophical
logic is not concerned with the psychological processes connected with thought,
or with emotions, images and the like. It is concerned only with those entities
ã thoughts, sentences, or propositions ã that are capable of being true and
false. To this extent, though, it does intersect with philosophy of mind and
philosophy of language.
What
is "political philosophy"?
It is the
study of fundamental questions about the state, government, politics, liberty,
justice, property, rights, law and the enforcement of a legal code by
authority: what they are, why (or even if) they are needed, what makes a
government legitimate, what rights and freedoms it should protect and why, what
form it should take and why, what the law is, and what duties citizens owe to a
legitimate government, if any, and when it may be legitimately overthrownãif
ever. In a vernacular sense, the term "political philosophy" often
refers to a general view, or specific ethic, belief or attitude, about politics
that does not necessarily belong to the technical discipline of philosophy.
Three central
concerns of political philosophy have been the political economy by which
property rights are defined and access to capital is regulated, the demands of
justice in distribution and punishment, and the rules of truth and evidence
that determine judgments in the law.
Who
are the major political philosophers, that directly impacted the American
political system?
-
Plato
-
Thomas
More
-
Thomas
Hobbes
-
John
Locke
-
Jean
Jacques Rousseau
-
Adam
Smith
Do
we really
need to know all this?
No. It is just
an interesting field to explore. You need to know the basic definitions, which
I will outline in class, and the basic set of political philosophers,
ditto.
