Hi again Catholic Catholic,
I'm interested in what would be the correct rules for thinking.
Jacafamala
Jacafamala,
Thank you for your question!

I think it is really wonderful that you want to know this! ;) I would hope that this would be true of everyone!
The answer to your question, of necessity, requires a certain amount of technical language, for which I apologize in advance.
By the same token, I will try to familiarize you with only a tiny fraction of the basics.
Therefore, I will try to be as brief and as lucid as possible.

The
rules, or more correctly, the
laws, for correct thinking ascertain the Truth of a subject with absolute objective scientific certitude.
As a result, these
rules or
laws, which are properly used by the intellect (one of the powers of the immortal Soul), or human mind, enable the mind to correctly function with order, ease, and without error (i.e. with absolute scientific certitude), when one masters these said
rules or
laws.
After a person has done this, the person is then able to expound one's thoughts orderly, clearly, systematically, and logically.
Although I do not have a brief list of these
rules or
laws, nevertheless, they can be found, usually within their respective explanations, in various sources.
Historically, in the Roman Catholic Church, these
laws of correct thinking are to be found in books that are written on what is called the
philosophia perennis (
perennial philosophy) which, after the 13th Century, came to be known as
Scholastic Philosophy, a.k.a. the
Philosophy of the Schoolmen, e.g. Saint Thomas Aquinas.
Scholastic Philosophy has moved down through the centuries to our own day, often obscured, often ignored, often, and for long time periods, despised as outmoded by those who knew, and continue today to know, little or nothing of its doctrines,not to mention its very compelling evidence.
Scholastic Philosophy has a number of what are called
departments, or if you prefer,
branches.
The
department or
branch of
Scholastic Philosophy which has to do with the
laws, for correct thinking is called
Epistemology.
To be complete,
Epistemology is also known as: 1) Major Logic; 2) Material Logic; and, 3) Criteriology).
The science of
Epistemology, by whatever name it is called, has to do with the trustworthiness of human knowledge. Since this is concerned with the mind and its knowing, it is in the
Department of Logic.
Here is where the nature and classification of Truth is to be found. Here is where Truth and certitude, the various doctrines on certitude, the sources of certitude, plus scientific certitude and its acquisition are investigated and learned.
For the record, some of the other
departments or
branches of
Scholastic Philosophy include: 1) Cosmology; 2) Psychology; 3) Theodicy/Natural Theology; 4) Ethics/Moral Philosophy.
Anyone who might be interested in reading about
Scholastic Philosophy might find the book by Cardinal Mercier to be helpful? It is called
A Manual of Modern Scholastic Philosophy. Both volumes one and two are available for free in a pdf file format on the following contents page (simply scroll down the page to find them) at:
http://www.archive.org/search.php?query=CARDINAL%20MERCIERBy the way, this particular source has lots of Roman Catholic Books in its archives - all free, and most in pdf file format.
I have found it interesting how some authors prefer
Scholastic Philosophy to what some might want to call
Augustinianism which some Philosophers style
neo-Platonism.
This is found to be the case with one well-respected Roman Catholic source which explains why Saint “Thomas Aquinas was a necessary corrective to Augustine. He is less great, less original, and, above all, less animated; but the calm didactics of his intellectualism enable him to castigate Augustine’s exaggerations with rigorous criticism, to impart exactitude and precision to his terms -- in one word, to prepare a dictionary with which the African Doctor may be read without danger” (
The Catholic Encyclopedia, Volume II, Teaching of St. Augustine of Hippo, I. His Function as a Doctor of the Church, (4) The character of his genius.)
As you can gather from the above, concerning
the laws of correct thinking, it is not just a matter of listing them, but, more importantly, of understanding the mentality in which and by which they are stated, explained, and taught. In other words, these
laws of correct thinking are really basic concepts of the Truth which are proven by
scientific certitude.
IF you are looking for something that is reasonably
short and simple,

you might find it almost as profitable (maybe even more so

), to review a few basics about
fallacies? Fallacies are those things which are false as opposed to those things which are True.
Personally, I have found that a basic knowledge of
fallacies has helped me greatly in the past. They are, in some respects, much easier for some people (like me

) to understand than the more
complicated laws of correct thinking!
As a courtesy to you, rather than not give you any details at all about any of these things, which would certainly be frustrating to say the least (I know it would be this way for me, anyway :help:), it seems both wise and prudent to present to you a brief list of at least some of them, even if some of the language tends to be somewhat technical.

But, not to worry, ;) I am not going to go into any details explaining them. Rather, you might find the book by Cardinal Mercier doing a much more reasonable job explaining some of them? There are also other books on this subject by other authors from the early to middle 1900's.
For example: IF you prefer something about as simple and as easy to read as possible, you might want to contact used book dealers and ask for the book by Right Rev. Msgr. Paul J. Glenn, Ph.D., S.T.D.: “An Introduction to Philosophy” (1930’s or 1940’s edition) and/or “Epistemology”, also by Right Rev. Msgr. Paul J. Glenn, Ph.D., S.T.D. (1930’s or 1940’s edition).
A one, short paragraph, technical explanation of all fallacies in general is found in Saint Thomas Aquinas'
Summa Theologica, Part I, Question 17, Article 4. The entire
Summa Theologica is available for free at:
http://stjamescatholic.org/summa/Summary of Fallacies
Fallacies can be summarized as follows:I. Fallacies arising from language (Fallacies of Diction).Fallacies of DictionAristotle listed six Fallacies of Diction which he called:
1) Equivocation;
2) Amphibology;
3) Composition or Compounding;
4) Division or Dividing;
5) Accent;
6) A Figure of Speech.
II. Fallacies arising from some other source (Extradictional Fallacies).A. Purely Logical FallaciesB. Semi-logical Fallacies1. Fallacy of Accident
2. Confusion of Absolute & Qualified Statement
C. Material Fallacies1. Begging the Question.
2. Irrelevant Conclusion/Missing the Point/Ignoring the Issue
3.
Argumentum Ad Hominem (Argument to the Man/Person)
4.
Argumentum Ad Populum (Argument to the People)
5.
Argumentum Ad Ignorantiam (Argument to Ignorance)
6.
Argumentum Ad Verecundiam (Argument to Authority)
7.
Argumentum Ad Baculum (Argument to Force)
8. False Cause
9. Complexity of Questions/Many Questions
III. Fallacies of InductionIV. Fallacies of Observation1. Fallacies of Non-Observation
2. Fallacies of Mal-Observation
a) Optical Illusions
V. Fallacies of Generalization1. Illicit Generalization
2. False Analogy
I hope that the above data has not been too overwhelming?
Likewise, I hope this this information, IF you have not already been familiar with it, will open an exciting new door to ascertaining the Truth of a subject with absolute objective scientific certitude.
So also, I would hope that the data, even though in an outline format, of fallacies will be of a great help to you in the future. I suspect most people already know what the fallacy of the
Argumentum Ad Hominem (Argument to the Man/Person) is all about?
Personally, I find it very interesting, but at the same time very disturbing, when I hear all kinds of politicians, especially during political debates on TV, whether for the U.S. Presidency, the U.S. Congress, etc., using psychobabble, as well as fallacies, to try to deceive voters by evading the real issues, evading telling the Truth, or victimizing voters with other deceptive methods of what is only superficial propaganda which sounds good, but is not good and sound!
Congratulations!
Your patience and fortitude have brought you to the conclusion of what I hope and pray has been an answer which has tried to point you in the correct direction of where to go for more information on this very important subject while, at the same time, trying to familiarize you with just a few of the basics involved.
I wish you well IF you decide to continue to explore this very interesting science!
Personally, in my humble opinion, it is sad that high school students are not given a class which teaches them (suitable for their level of learning capabilities) what the
laws of correct thinking are as well as what some of the more frequently used fallacies are.
IF this was done, perhaps there would be more peace in the world, with much fewer arguments, because Truth has really nothing to do with a person's personal opinions about anything, but rather focuses only on the Truth of a subject with absolute objective scientific certitude! Likewise, maybe politicians would suddenly stop victimizing voters who know when and what fallacies these slick-talking politicians are trying to use to deceive the voters? Maybe this would force at least some politicians to be totally honest with voters by telling them the Truth, not what the politicians think the voters want to hear?
Thanks so much for taking time from your busy schedule to read this!
God Bless You!
