Practical arguments

Practical arguments

Practical arguments are a logical structure used to determine the validity or dependencies of a claim.See argument for uses and general information.

Overview

An argument can be thought of as two or more contradicting tree structures.
*The root of each tree is a claim; A belief supported by information.
*The root branches out to nodes that are [http://en.wiktionary.org/wiki/ground grounds] ; supporting information.
*The edges connecting them are [http://en.wiktionary.org/wiki/warrant#Transitive_verb warrants] ; rules or principles.
*Claims, grounds and warrants are often not known for certain, so they are presented with a qualifier to indicate their probability.
*When a ground is disputable it is a sub claim, in this way the tree can grow to be quite large.

The object of a discussion is often to resolve a difference of opinion.This requires common grounds from which to logically convince your opponent that your claim is better supported and that their claim is supported by false grounds and or warrants. (see Occam's razor) If one has no grounds or warrants to support ones claim, then one has no argument just a belief/claim, probably an inaccurate one.

Example 1:


*Claim: Cats are less intelligent than dogs.
*Ground: Cats cannot learn to do tricks as well as dogs do.
*Warrant: The ability to learn tricks is a mark of intelligence.

Example 2:

:Where: C=claim, W=warrant, G=ground, and Q=qualifier

*C: Humans can't fly.
