Logical Gal and the difference between objective terms and subjective values

4 Nov

Last time I wrote (post dated 1 Nov 2013),

I asserted that terms were by nature objective since they are descriptive of what is.

One of the laws of the universe (no human made this up) is called the Law of Identity.  An apple IS an apple.  All the attributes on the left of the IS add up perfectly to what is on the right side.   Add or subtract one of the attributes and you no longer have an apple.

I asserted that the definition of TRUTH is straightforward – It is that which corresponds to reality.

So where do values and opinions come in to play?  Can they be subjective?

Value statements depend on the presuppositions behind them.  Presuppositions are the assumptions we make that are often hidden.  But they totally influence our conclusions, our values!

Change the presuppositions and you alter the sense of the conclusion. Presuppositions are sometimes unarticulated in a discussion.  When you have just a partial argument, it’s called an ‘enthymeme’ because the missing parts are implicit.  

“You’ll get fat!”   when fleshed out could be part of a syllogism that looks like this:

  • Eating chocolate 3x a day causes people to get fat – (Presupposition)
  • You’re eating chocolate 3 x a day – (Presupposition)
  • Therefore, you’ll get fat – (explicit enthymeme that showed up just as conclusion)

Getting fat is a fact, it’s truth.  What I mean is:  ‘adding a pound of fat to your body‘ is what might be corresponding to reality  But again, depending on one’s values, being fat is either a sign of ill health, or a sign of prosperity and beauty. (Think of Rubens’ artwork!)

 

The fact of adding fat is the truth – it’s objective.

But what it means is relative and subjective to the one creating the proposition.  In the conclusion above, the proposition being asserted is this:  You (subject) are doing something that will cause you to get fat. (predicate)

That proposition is either objectively TRUE or FALSE.

It’s subjective sense is, however, relative…..relative to the assumptions/presuppositions one holds.

Clear thinking requires the use of tools and the time to employ them.  Asking questions and parsing out terms from propositions is one tool.  Teasing out the implicit ideas behind the propositions is another.  Be a diligent detective.
