PHILOSOPHY 104
Chapter 5.1
Stuff to include in and leave out of the
standard form argument
Tangents
• Not all statements a person makes in the course of an
argument are necessary for stating their argument.
• Many claims are related but are tangential.
• It is not necessary to put these claims in the standard
form argument
Repetition
• Whether from awkwardness or rhetorical purpose,
repeating the same idea several times in the course of an
argument does not add anything to the standard form
argument.
Make terms consistent
• Say someone discusses “economic troubles”, “financial
hardships”, a “credit crisis”, “poor stock market
performance”, etc. all in the same article but at different
points.
• People often use synonymous words or phrases just for
variety. When they do this, it is okay to condense them to
make the standard form argument look neater
• Sometimes, however, authors use similar but distinct
language to be precise.
Condensing:
Main argument:
Cleaned up:
P1. Spendthrift government
policy has led to a credit
crisis.
P2. Bad economic
performance always
generates more
government spending.
C. If the cycle isn’t broken,
then financial hardship will
continue.
P1. Deficit spending has
caused bad economic
performance
P2. Bad economic
performance will cause
additional deficit spending
C. If deficit spending
continues, then bad
economic performance will
result.
Example (claims that work together):
• (1) Bill is a student at Yale. (2) No student at Yale has won
the Nobel Prize. (3) Therefore, Bill has not won the Nobel
Prize.
1 + 2

Example (independent claims):
• (1) The president is soft on the environment. (2) He has
weakened clean-air regulations (3) and lifted restrictions
on logging in the West.

Example: (complex arguments)
• Conclusion: (3) The idea that God is required to be the enforcer of the moral law is not
plausible. Premises: (4) In the first place, as an empirical hypothesis about the
psychology of human beings, it is questionable. (5) There is no unambiguous evidence
that theists are more moral than nontheists. (6) Not only have psychological studies
failed to find a significant correlation between frequency of religious worship and moral
conduct, but convicted criminals are much more likely to be theists than atheists. (7)
Second, the threat of divine punishment cannot impose a moral obligation. (8) Might
does not make right.
Chapter 5 Exercise 2 #4
Mercury is known to be the only metal that is liquid at room
temperature, so a pound of mercury would be liquid in this
room, which is at room temperature, and it would also
conduct electricity, since all metals do. Therefore, some
liquids do conduct electricity.

Chapter 5 Exercise 2 #4
1: Mercury is known to be the only metal that is
liquid at room temperature.
2: This room is at room temperature
3: A pound of mercury would be liquid in this room,
4: All metals conduct electricity.
5: A pound of mercury would conduct electricity.
6: Some liquids do conduct electricity.

1: Mercury is known to be the
only metal that is liquid at
room temperature.
2: This room is at room

3: A pound of mercury would
be liquid in this room,
4: All metals conduct
electricity.
5: A pound of mercury would

6: Some liquids do conduct
electricity.

required to work
together to support 6,
