You can't DECIDE to believe in something.


Critics say:

You can't DECIDE to believe in something.

You can't decide to believe that invisible pink elephants exist.

You can't decide to believe that invisible pink elephants exist.

You can't decide to believe that God exist.

You can delude yourself, but deep down you know it's not real.


That is all true, but you can decide to fairly evaluate the facts, evidence, and arguments to evaluate questions like:

1) Is reason the basis for all knowledge? If not reason, then what is it? Can you defend this sans reason?

2) Do you acknowledge that the inference to the best explanation is how most if not all field of inquiry gain knowledge? Meaning, the hypothesis or theory that best explains all [or most] of the data is held to be true.
 
3) What is reality, and how do you know?

4) What best explains the origin of physical reality?

5) What best explains the origin of information in DNA?

6) What best explains human reasoning?

7) What best explains morality?

8) Is there one hypothesis that best explains all of those questions?

One explanation would be a rational, extremely powerful, intelligent designer, moral person, existing outside the physical part of reality. What most would call God. 

What is the naturalistic explanation for all of those things above?

The Three Laws of Logic

As good critical thinker should be well acquainted with the three founding principles of informal logic, the form of logic generally used in debates and arguments.

Understanding of basic logic is important to effectively be able to get across your reasons for being holding the views you have, as well as being able to identify flaws and fallacies in your interlocutor's arguments. So, a good idea to quickly go over the three “laws” of informal logic, how they work and why they are important.

It is one of the pivotal assumptions of western civilization is that there are certain fundamental principles which govern human thinking. They are considered as fundamental in the sense that without these laws, reasoning cannot take place. 

In western tradition, the concept of laws of thought can be traced back to Aristotle (384-322 BCE), the eminent Greek thinker, who is considered to be the pioneer of western logic. Before him, the geometricians and the arithmeticians used proofs in their respective domains. Aristotle was the first to extend the study of formal proof in the domains beyond the realms of geometrical and mathematical thinking. He was also the first to investigate the patterns embedded in human reasoning and the way in which reasoning is processed. 

As part of his project, Aristotle was trying to describe the basic laws by which human thought (and reasoning) can occur.  laws so fundamental that obedience to them is both necessary and sufficient condition for correct thinking. These three laws have traditionally been called:

1) The Law of Identity: “A is A” or “Anything is itself”. If a statement is true, then it is true. It asserts that every statement of the form pp is true, that is it is a tautology. 

2) The Law of Excluded Middle: Anything is either A or not A. Any statement is either true or false – asserts that every statement of the form p V p is true, it is a tautology. 

3) The Law of Contradiction: Nothing can both be A and not A. No statement can be both true and false – asserts that every statements of the form pp is false. 

These are now explained below: 

Law of Identity 

By law of identity, we mean that everything is the same with itself and different from another, e.g., B is B and not B. It says that if any statement is true, then it is regarded only as true. It also means that every statement of the form pp must be true, so the statement is a tautology. Aristotle also talks about the laws of identity. 

It has been also said that each thing like of universal or a particular is composed of its own unique set of features. Things, which have the same essence refers to the same thing, whereas things that have different essence refers to the different thing. Those who violate the law of identity are engaged in the informal logical fallacy, we mean equivocation

Law of Non-Contradiction 

This law of non-contradiction comes under the domain of logic. It says that “one cannot say of something that it is and that it is not in the same respect and at the same time”. This definition is given by Aristotle. 

It also says that no statement can be both true and false. So, it has been said that every statement of the form p⋅~p must be false, then that statement is regarded as self-contradictory. It has been said that the law of non-contradiction or the principle of non-contradiction means the same thing. It also states that contradictory statements cannot both be true in the same sense at the same time. By the law of non-contradiction, we mean an expression of mutually exclusivity.

Law of Excluded Middle

The law of excluded middle comes under the domain of logic. It also means the principle of excluded middle. 

  • It says that either the proposition should be regarded as true or its negation should be regarded as true. 
  • It is also known as the law or principle of the excluded third. 
  • It says that a statement is either true or false. 
  • It has been said that there is no middle ground between being true and being false. 

This law excludes a middle ground between truth and falsity. It has been also state that every statement of form pv~p must be true, then that every such statement is regarded as tautology. 

Pushbacks:

The law of identity has been attacked on the ground that things change, and are always changing. Thus, for example, statements that were true of the United States when it consisted of the 13 original states are no longer true of the United States today with 50 states. But this does not undermine the principle of identity. The law of identity is true, and it does not interfere with our recognition of continuing change. 

The law of non-contradiction has been attacked by on the ground that the world is replete with the inevitable conflict of contradictory forces. The reply is that there are conflicting forces in the real world is true, of course – but to call these conflicting forces “contradictory” is an ambiguous use of that term. Labor unions and private owners of industrial plants may indeed find themselves in conflict – but neither the owner nor the union is the “negation” or the “contradictory” of the other. The principle of contradiction understood in the straightforward sense in which it is intended by logicians is unobjectionable and perfectly true

The saw of excluded middle has been objected to on the ground that it leads to a “two valued orientation” that is, everything in the world must be either “white” or “black”. This objection also arises from the misunderstanding. Of course, the statement “This is black” cannot be jointly true with “This is white” – where “this” refers to exactly the same thing. But although these two statements cannot both be true, they can both be false “This” may be neither black nor white; the two statements are contraries, not contradictory. The contradictory of the statement “This is White” is the statement “it is not the case that this is white” and one of them must be true and the other false. The principle of excluded middle is inescapable.

Reason is the basis for knowledge



Reason is the basis for knowledge and therefore the way to determine what is true.

For example, under empiricism [the philosophical view that knowledge comes from sensory experience and observation] they will use reason to formulate a hypothesis, construct an experiment, and evaluate the result. So, an empiricist will, in fact must, appeal to logic/reason to obtain knowledge. And this is true for any other schools of thought – everyone will appeal to reason to defend their view as well as criticize/evaluate other views

Reason or Critical thinking is the act or practice of careful goal-directed thinking (i.e applying reason and questioning assumptions) to solve problems, evaluate information, discern biases, etc. The 
Stanford Encyclopedia of Philosophy states: One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. We use Critical thinking for analyzing and/or evaluating information gathered from various sources as a guide to convictions and action in everyday life and in all fields of inquiry. 

A Christian may say that revelation is knowledge, but they must still reason from the Scriptures, as in Acts 17:2,17

Note: if one uses reason to criticize my claim, that's actually validating it - you are using reason to gain knowledge as to the validity of my claim.

Objection 1: Rationalism begs the question - the rationalist will use a rational argument as a premise for the conclusion of his argument.

Reply: To this, I say no, it is testing a hypothesis. Test all epistemic theories, see that all use reason.

Objection 2: I can use reason to gain knowledge about the Lord of the Rings. I can gain knowledge about a fictional universe, but that doesn't make it magically true for our reality

Reply: If one is gaining knowledge about the LOTR, then they should be able to gain the information that it's fictional.

Objection 3: One must use evidence along with reason to conclude they’ve learned something about reality and not about something in their (or someone else’s) imagination. Otherwise, there is no way to differentiate between knowledge about reality and knowledge about fictional universes.

Reply: First, notice that you did not use evidence in this, so you seem to have refuted your own point. Secondly, you cite "reality"; what is it, and how do you know?

Objection 4: Your appeal to “reasoning” as absolute authority is circular. You assert that “reasoning” is the ultimate authority because that is the only reasonable means for ascertaining truth.

Reply: Circular reasoning is when the proposition is supported by the premises, which are supported by the proposition, creating a circle in reasoning where no useful information is being shared.

But my argument stems from the fact I investigated other schools of thought until it dawned on me that everyone uses logic or reasoning to make their case, including empiricists, skeptics, intuitionists, etc.

Note: These pushbacks come from previous conversations about this topic.

To sum up,

1) reason alone can be used alone to gain knowledge 
 
2) every other method must employ reason to gain knowledge, otherwise their preferred epistemological model doesn't work
 
3) All criticisms of my view will invariably use reason to validate their analysis.
