Appeal To Consequences

November 29th, 2009 No comments

Taxonomy – Where am I?

Appeal To Consequences (argumentum ad consequentiam)

classification : informal – appeals to motives in place of support

An argument that concludes a premise (typically a belief) to be either true or false based on whether the premise leads to desirable or undesirable consequences.

Foundations

Based on an appeal to emotion since the desirability of a consequence does not address the truth value of the premise. Moreover, in categorizing consequences as either desirable or undesirable, such arguments inherently contain subjective points of view.

Sub Fallacies

Appeal to Force
Wishful Thinking

Red Herring

Quoting Out Of Context

Taxonomy – Where am I?

Quoting Out Of Context

classification : informal – fallacies of ambiguity

To quote out of context is to remove a passage from its surrounding matter in such a way as to distort its meaning.

Foundations

It is often included with the Fallacy of Accent.  However, Aristotle’s original Fallacy of Accent referred solely to shifting the accent on syllables within words, and it has already be stretched a little to include shifting the accent between words within a sentence. To expand it further is reason the concept of “quoting out of context” gets its own section.

Fallacious quoting can take two distinct forms; Straw Man and Appeal to Authority.

In A Certain Respect And Simply

November 25th, 2009 No comments

Taxonomy – Where am I?

In A Certain Respect And Simply

classification : informal – Non-sequitur

Take an attribute that is bound to a certain area and assume that it can be applied to a wider domain than was originally intended.

Foundations

When we discuss an attribute of something or somebody, we implicitly assume that there is some constraining contextual factors. When the assumption is carried too far in this context, then this fallacy is committed.

Affirming The Consequent

Taxonomy – Where am I?

Affirming The Consequent

classification : informal – Non-sequitur

Affirming the consequent argues backward from the truth of a conclusion to the truth of one of the propositions like this.

Foundations

Together with its similar Sub fallacy, Denying the Antecedent, instances of Affirming the Consequent are most likely to seem valid when we assume the converse of the argument’s conditional premise.

Bulverism

Taxonomy – Where am I?

Bulverism

classification : informal – Non-sequitur

Rather than proving that an argument is wrong, a person instead assumes it is wrong, and then goes on to explain why the other person held that argument..

Foundations

The term “Bulverism” was coined by C. S. Lewis. Lewis wrote about this in a 1941 essay of the same name, later included in the anthology God in the Dock. It is very similar to Antony Flew’s “Subject/Motive Shift”.
