Philosophy 2801 - Introductory Lecture

2 Kinds of Philosophy

1. Presenting a world view
2. Arguing for a particular world view (or part of one)
#2 is our concern here.

*******************************
Some Boring (But Important) Technical Points

Definition of an argument: a set of statements of which it is claimed that one of those statements (the conclusion) is supported by the others (the premises).
E.g., Sydney is in Cape Breton
Cape Breton is in Nova Scotia
Therefore Sydney is in Nova Scotia.
When we're analyzing an argument, we're going to adopt the practice of labelling the premises of an argument as P1, P2, ... and the conclusion as C.  Hence, the boring argument above becomes.
P1: Sydney is in Cape Breton
P2:  Cape Breton is in Nova Scotia
C: Therefore Sydney is in Nova Scotia.
Two Things to Look for in an Argument
1. True Premises
2. Logical Strength
Logical Strength - The premises should support the conclusion (i.e., the conclusion should be likely to be true if the premises are true - the more likely, the better).

Roughly, philosophy can be divided up into four areas.

1. Logic
2. Metaphysics/Ontology - investigates what there is
3. Epistemology/Theory of Knowledge - ingestigates how (and what) we know about what there is
4. Value Theory  - e.g., ethics, political philosophy, aesthetics, etc.
Philosophy can also be carved up in a way that cuts across these areas, i.e., by the subject of interest about which philosphical questions are to be asked. Some examples:
Philosophy of Biology
Philosophy of Physics
Philosophy of Education
Philosophy of Technology

Philosophy of Technology

Asks questions about about how technology affects us as well as ethical questions about what we should do with technology
E.g., Should human cloning be allowed? (Ethical)
How does the internet affect our ways of gathering knowledge about the world? (Epistemological)
Where are 'connected' individuals located? (Metaphysical)
What is real? (Metaphysical)
