When providing psychoeducational lessons about Rational Emotive Behavior Therapy (REBT), I often illustrate the relationship between logic and reason through use of syllogisms—a deductive scheme of a formal argument consisting of a major and minor premise, and a conclusion.
For context, that which is considered rational is based on or in accordance with both logic and reason. Here, logic is a particular mode of reasoning viewed as either valid or faulty. As well, reason is merely a statement offered in explanation or justification (i.e., the logic follows).
Furthermore, stating that “logic follows” means that a syllogistic conclusion is reached based on a set of premises which are connected through reasoning that is sound—free from error, fallacy, or misapprehension, as a view about what is or isn’t sound may vary from the views of others.
Commonly, sound logic implies that the conclusion is a necessary outcome of the given information that adheres to the rules of logic. Essentially, suggesting that logic follows is an indication that if the premises are true, then the conclusion empirically must also be true.
However, if logic doesn’t adhere to syllogistic form, then it’s said not to follow. This is a notable consideration when teaching the tenets of REBT and how beliefs are formed, how they function, and the ways in which they influence cognitive, emotive, sensational, and behavioral outcomes.
Regarding the rule of syllogism, there are three parts involved which relate to a conditional arguments, categorical propositions, or disjunctive proposals. Forming this connective stance is a hypothesis—an assumption or concession made for the sake of argument.
In particular, the hypothesis is the conditional statement that follows after the word “if.” Thereafter, the inference—a conclusion or opinion that is formed, because of known facts or evidence—follows after the word “then” (i.e., if […], then […]).
Representing each phrase of the conditional, categorical, or disjunctive statement is a letter or variable (e.g., x). Generally, syllogisms are arguments which usually propose two statements (“premises”). There’s a major and minor premise, and a resulting conclusion.
The major premise expresses a general point while a minor premise puts forth a particular argument. Based on both statements, a conclusion is the final product of the proposition. Bear in mind that simply because an argument follows logical form doesn’t mean that it is reasonable.
This is why I find utility in illustrating syllogisms when practicing REBT. Often, a person’s proposition, argument, thought, or belief which is based on logical form doesn’t necessarily result in a well-justified explanation that relates to rationality.
Admittedly, my approach to syllogistic use in REBT doesn’t delve too deeply into equivalence modes or mathematical formulations where are associated with formal logic. Rather, I merely seek to introduce people to descriptive formulas which underpin beliefs.
This is done in respect to assessing for beliefs which are irrational—those which aren’t in accordance with both logic and reason. It’s worth noting that not all irrational beliefs are self-disturbing propositions.
For instance, person X may genuinely believe that the Earth isn’t spherical. All the same, simply because other individuals disagree with person X, he doesn’t upset himself about their differing attitudes. Instead, person X merely shrugs off the difference in opinion and carries on with life.
Noteworthy, there are four major irrational beliefs and five major characteristics of these self-disturbing assumptions recognized in REBT theory:
Irrational beliefs –
1. Global evaluation – “Life isn’t worth living if I’m not accepted by other people.”
2. Low frustration tolerance – “I can’t stand not being accepted by other people.”
3. Awfulizing – “It would be awful if I weren’t accepted by other people.”
4. Demandingness – “I must be accepted by other people.”
Characteristics –
1. Rigid or extreme
2. Conducive to psychological disturbance and impaired interpersonal relationships
3. Unhelpful to you as you strive towards your goals
4. False
5. Illogical
It’s with this understanding that I advocate use of syllogistic practice when disputing irrational beliefs, as this is a core component of the ABC model that is associated with REBT. Noteworthy, in a blogpost entitled Tautology, I stated:
A rhetorical tautology may be described as saying of the same thing twice in different words, generally considered to be a fault of style (e.g., they arrived one after the other in succession). In other words, it’s superfluously redundant.
On the other hand, a logical tautology is a proposition that is always true, because it excludes no logical possibilities. Such statements provide nothing of value. For instance, “I’ll either make a salient point in this blogpost or I won’t.”
Quite often, I hear tautologies expressed by people who may think that they’re making salient points regarding justification for irrational beliefs when in fact they aren’t. Without further ado, I present examples of logical tautology forms so that you can understand what I mean:
Form (tautology 1) –
p is true is equivalent to p is true or p is true.
Example –
Proposition: Disputation is challenging is equivalent to disputation is challenging or disputation is challenging.
Stated differently: Disputation is challenging is equivalent to disputation is demanding or disputation is difficult.
Simplified tautology: Either disputation is demanding or it’s difficult.
Form (tautology 2) –
p is true is equivalent to p is true and p is true.
Example –
Proposition: Disputation is challenging is equivalent to disputation is challenging and disputation is challenging.
Stated differently: Disputation is challenging is equivalent to disputation is demanding and disputation is difficult.
Simplified tautology: Disputation is demanding and it’s difficult.
While not a syllogism, I find it valuable to illustrate how belief values don’t necessarily change when exchanging “and” (conjunction) or “or” (disjunction). Of course, not all tautological inferences use these terms (e.g., In my opinion, I think you’ll understand what I mean.).
Essentially, as a rule of inference, a tautology uses the rule of replacement regarding one term and another which are synonymous or which share the same meaning. Basically, a tautology is a repetitive proposition similar to stating, “It is what it is.” You either understand or don’t.
