Explain what is meant by the affirming the consequent fallacy.
Give an example to support your answer. (2)
Candidates can gain 1 mark by demonstrating their understanding of the affirming the consequent fallacy.
Any of the following points are acceptable:
in this fallacy it is incorrectly assumed that the fact that Q is true guarantees that P is also true (1 mark)
in the affirming the consequent fallacy it is incorrectly assumed that Q is a sufficient as well as a necessary condition for the truth of P (1 mark)
given the truth of ‘If P then Q’, the truth of Q is a necessary but not a sufficient condition for the truth of P (1 mark)
Award 1 mark for a correct example of affirming the consequent, for example:
P1: If you miss the bus then you will be late for school. P2: You were late for school.
C: You must have missed the bus.
Explain the difference between an analogy used as part of an argument and an analogy used as an explanation. (2)
Award 1 mark for each of the following points:
an account of how analogies are used in arguments, for example analogical arguments work by saying that X is true of A so X is probably also true of B because B is relevantly similar to A (1 mark)
an account of how analogies are used as explanations, for example analogical explanations work by comparing something familiar or easy to imagine with something that is difficult to understand (1 mark)
In your Higher Philosophy course you have studied what makes premises in an argument acceptable.
State any two examples of what might make premises in an argument unacceptable. (2)
Award 1 mark each for any two of the following points:
the premise is ambiguous (1 mark)
the premise can’t be accepted as true (1 mark)
the premise appeals to an inappropriate authority (1 mark)
the premise does not properly represent the facts pertaining to the conclusion (1 mark)
Read the following passage and answer the question that follows.
‘If I exercise regularly then I will live a long and healthy life. But since I am not going to exercise regularly then I will not live a long and healthy life.’
Explain what is wrong with this type of argument.
In your answer you should focus on identifying and explaining a fallacy. (2)
Award 1 mark for identifying the fallacy of denying the antecedent.
Award 1 mark for an explanation of the fallacy, for example:
given the truth of ‘If P then Q’, the truth of P is a sufficient but not a necessary condition for the truth of Q (1 mark)
in the denying the antecedent fallacy it is assumed that P is a necessary as well as a sufficient condition for the truth of Q (1 mark)
Award 1 mark for accurate reference to the given argument, for example:
the fact that P is false does not guarantee that Q is also false — with reference to the example, the person not exercising may still lead a long and healthy life (1 mark)
exercise isn’t the only factor in living a long and healthy life — for example, genetics may play a big part (1 mark)
Read the following passage and answer the question that follows.
‘Surely you know that we have a duty to pay our taxes. It’s because we get a health service and other benefits from government activities. We have a duty to do our share to finance these activities. And taxes are the way we do that. Stop moaning! Pay your taxes!’
Write the argument in the above passage in standard form. (3)
Candidates can gain marks as follows:
for putting the argument into standard form, that is, laying out premises and conclusion, each taking a separate line and labelled accordingly (1 mark)
for recognising that ‘taxes are the way to finance a health service and other benefits from government activities’ is an intermediate conclusion (1 mark)
identifying the final conclusion (1 mark)
A correct representation of this argument in standard form would
be:
P1: We get a health service and other benefits from government activities.
P2: Taxes are the way to finance a health service and other benefits from government activities.
Intermediate conclusion: We have a duty to do our share to finance a health service and other benefits from government.
Conclusion: We have a duty to pay our taxes.
Read the following passage and answer the question that follows.
‘Think again about what you’ve said. The Santa lie is morally justified. For a start, the lie is not permanent. You give kids the myth about Santa now but you tell them the truth when they’re older. It’s a mild deception. When kids grow up they accept that Santa isn’t real and remember the years of pleasure. Believing in Santa makes Christmas magical and perfect. Get a life!’
Present the argument in the above passage in an argument diagram. You should provide a suitable key to your diagram. (3)
Award 1 mark for a convergent argument diagram.
Award 1 mark for identifying the conclusion, ‘The Santa lie is morally justified’.
Award 1 mark for providing an appropriate key with statements labelled and omitting both ‘Think again about what you’ve said’ and ‘Get a life’.

Diagram
Give an example of an argument which fits the following diagram. (1)
Award 1 mark for any correct example of a linked argument.
For example:
P1: Socrates is a man. P2: All men are mortal. C: Socrates is mortal.
Arguments are often evaluated in terms of acceptability, relevance and sufficiency. To what extent are the premises in the following argument acceptable, relevant and sufficient to draw the conclusion?
‘Swimming is a safe exercise for people who have joint problems such as arthritis, because the water supports the swimmer. Furthermore, there is no stress on painful joints such as the ankle and knee.’ (3)
Award 1 mark for any of the following points: The premises are acceptable:
on the grounds that they are common knowledge
because it is known to be true
because it can be accepted as true
Award 1 mark for the following point:
The premises are relevant because some justification is provided to support the conclusion — the water supports the swimmer or there is no stress on painful joints.
Award 1 mark for the following point:
The premises are acceptable and relevant — they are sufficient to have confidence in the conclusion.
Evaluate the following argument. You should refer to acceptability, relevance and sufficiency in your answer. ‘The class notes for the geology course were difficult to read. The assignments for the class were hard to complete. Many pupils don’t enjoy geology. Therefore, the lecturer in the geology course was not competent in his knowledge of geology.’ (3)
Award 1 mark for saying that the premises are insufficient to draw the conclusion.
Award marks for other appropriate comments, for example:
Even if each individual premise is true and therefore acceptable none of the premises is relevant to the conclusion (1 mark) that ‘the lecturer in the geology department was not competent in his knowledge of geology’. (1 mark)
Even if it is the case that the class notes were difficult to read, the assignments hard to complete, and the pupils don’t enjoy geology, the lecturer might well be very competent in his knowledge of geology. (2 marks)
(a) What is a fallacious appeal to emotion?
b) Why might a fallacious appeal to emotion affect the relevance of premises in an argument? (1 each
Award 1 mark for either of the following points:
A fallacious appeal to emotion is an attempt to gain acceptance of a claim by appealing to some emotion rather than a reasoned appraisal of the facts. (1 mark)
The premises stated by the arguer might not be relevant to their conclusion because they may play on emotion to manipulate the audience rather than on the argument. (1 mark)
dentify and explain the fallacy in the following argument. You should refer to this argument in your answer.
‘Very soon after the politician made his speech at the museum, a devastating explosion happened. For the safety of the people who live and work in that area of Edinburgh, it is essential that the politician makes no more speeches there.’ (3)
Award 1 mark for identifying the Post Hoc Ergo Propter Hoc fallacy.
Award 1 mark for explaining the Post Hoc Ergo Propter Hoc fallacy, for example:
This informal fallacy is falsely assuming that because some event followed another that it was caused by the first event, that because X and Y occur one after the other, the one causes the other. (1 mark)
Award 1 mark for explaining the Post Hoc Ergo Propter Hoc fallacy in relation to the given argument, for example:
Just because there was a devastating explosion very soon after the politician made his speech does not mean that there was a causal link between the two events. (1 mark)
State three purposes of Descartes’ method of doubt. (3)
Award 1 mark for any of the following points:
to find a firm foundation for knowledge (1 mark)
to find something firm and lasting in the sciences (1 mark)
to prove that God exists (1 mark)
to prove the sceptics wrong (1 mark)
to eliminate all sources of doubt (1 mark)
to make a case for rationalism (1 mark)
This list is not exhaustive — award marks for any other accurate points.
Outline Descartes’ dream argument. (4)
Award 1 mark each for any relevant point and an additional mark for a development of that point.
Candidates may explain the dream argument in different ways, but they might cover the following points:
There are no certain signs that distinguish my waking life from being asleep and dreaming. (1 mark)
If there are no certain signs that distinguish my waking life from being asleep and dreaming, then it is possible that I am not awake right now but rather dreaming I am awake. (1 mark)
It is possible that I am not awake right now but rather dreaming I am awake. (1 mark)
Descartes concludes that if he is dreaming right now then the beliefs he has gained from his senses may be open to doubt and could in fact be false. (1 mark)
Descartes recognises that, even if everything is a dream, some simple and universal things are still real such as the truths of mathematics. (1 mark)
Why does Descartes think the Cogito is a certain truth? (4)
Award 1 mark each for any relevant point, for example:
Descartes says that the proposition ‘I am, I exist’ is necessarily true whenever it is put forward by me or conceived in my mind. (1 mark)
If this proposition is necessarily true, then it is a certain truth. (1 mark)
The certainty is logical — Descartes can’t doubt that he is thinking. (1 mark)
The cogito is Descartes’ absolute certain truth and he sees this clearly and distinctly. (1 mark)
If it were possible that he could have such a perception and it be false, then he would not be able to trust in the cogito.
(1 mark)
A non-deceiving God guarantees the truth of clear and distinct perceptions. (1 mark)
Explain the purpose of Descartes’ examples of stones and heat in Meditation III. (4)
Award 1 mark each for any relevant point and an additional mark for a development of that point.
Award 2 marks for an explanation of Descartes’ position that:
something cannot arise from nothing (1 mark)
what is more perfect cannot arise from what is less perfect (1 mark)
Award 1 mark for Descartes’ claim that a stone cannot begin to exist without being created by something which contains all that we can find in the stone.
Award 1 mark for Descartes’ claim that heat cannot be produced in something that was not hot or at least that did not have ‘at least the same order of perfection as heat’.
