PLANNING AND CREATING YOUR REASONING 125


  • Do the premises cover all the aspects of the conclusion?

  • Are these premises well formed, with particular reference to the internal
    connections which they make?

  • Are they well founded (if not, then what support can they be given)?

  • Are enough reasons given to meet the requirements for breadth?

  • Are they expanded sufficiently to give depth to the argument/explanation?

  • Is each idea in the conclusion referred to in some way in these premises?

  • Are the premises grouped together properly?
    Just one example would be to state the following reason:


The Olympic games are now very expensive to organise.

This might break down, on further analysis, into claims such as:



  1. There are more sports, more athletes, and more coaches than ever
    before.

  2. Hosting all these events and people is very costly.

  3. Non-sport costs, associated with security and entertainment, are now
    much more prominent.
    (There are, of course, many more possible premises.)
    Third, think about the analytical relationships between the premises and the
    conclusion (as seen in the diagram). Here, we can think about the sort of reasoning
    that is being used:



  • Do the premises show the cause of an effect? (If so, are differences or
    similarities clearly stated?)

  • Do they state some generalisation that provides the knowledge we need about
    a specific conclusion? (If so, is the specific case really a member of the
    general category?)

  • Do the premises draw together specific cases so as to make a generalisation?
    (If so, are these specific cases representative of the general category?)

  • Is it an analogical relationship, in which similarities between the events
    described in the premises and the conclusion provide the answers we are
    seeking? (If so, are the events consistent with one another?)

  • Is it simply reasoning from terms, with the claim simply establishing the
    particular meaning of the conclusion? (If so, are we making it clear?)
    In each case, remember that these questions unlock relationships. We can analyse
    events by thinking about 'What is the cause of X?' or 'What effects does X cause?'; we
    can think about the way that many cases of X might prompt us to generalise, or about
    how X might only be explicable as a specific case of some general rule.
    Continuing the previous example, the premises concerning cost are about the
    cause of the increased commercialism of the games. Because of the need for money
    to fund the games (a result of these costs), there is no way they could be staged
    without corporate funding. Good reasoning would involve checking to see if it
    really is the case that increased costs is the only factor; in doing so, we might find
