**It can be true even if it does not follow logic**. Because logic does not cover all aspect of life. The best explanation for logic is, discovering links between two things.

## Does logic have to be true?

**Logical truths are generally considered to be necessarily true**. This is to say that they are such that no situation could arise in which they could fail to be true. The view that logical statements are necessarily true is sometimes treated as equivalent to saying that logical truths are true in all possible worlds.

## Can a logical claim be true or false?

**A claim is a sentence that can be true or false (but not both)**. Actually in logic texts the more commonly used term is “statement” or “proposition”. These are all intended to mean the same thing.

## Can a logical argument be wrong?

**Logical fallacies are flawed, deceptive, or false arguments that can be proven wrong with reasoning**. These are the most common fallacies you should know about.

## What makes logic true?

Specifically, “a sentence is logically true **if and only if it is true in every genuinely possible configuration of the world**.”11 Thus, logical necessities might be explained as those propositions true in virtue of the nature of every situation, or every object and property.

## Why is it important to use logic?

Why is logic so important? The answer is that logic **helps us better understand good arguments**—it helps us differentiate between good and bad reasons to believe something. We should want to have well-justified beliefs. We want to know what we should believe.

## How do you know if something is logical?

Therefore, in logic, there must be a set of rules, which would determine whether one’s reasoning is correct or incorrect. **If it were correct, it would be logical**. This is where the difficulty and ambiguity of logic come in.

## Are all logical truths tautologies?

Note that **every tautology is also a logical truth**, and every logical truth is also a TW-necessity. But the converse is not true: some logical truths are not tautologies, and some TW-necessities are not logical truths.

## What is truth in logic and critical thinking?

**When a statement is true, logicians like to say that it has T (truth) as its truth-value**. When a statement is false, its truth-value is F (falsehood). If a statement is neither true nor false, then we say it lacks a truth-value.

## What is truth and validity in logic?

VALIDITY. Truth is the complete accuracy of whatever was, is, or will be, error-proof, beyond doubt, dispute or debate, a final test of right or wrong of people’s ideas and beliefs. Validity is defined as the internal consistency of an argument.

## What is the difference between tautology and logical truth?

A “tautology” refers to a sentence of truth-functional logic where every valuation, every row of a complete truth table, evaluates to true. A “logical truth” is a sentence in first order logic where every interpretation is true.

## How is logic limited by partial truth?

Partial Truths

**Many forms of logic only handle true or false**. Where rational thought can easily see a glass as approximately half full. Logic tends to give you, false that the glass is full and false that it is empty. It should be noted that some forms of logic, including fuzzy logic, can handle partial truths.

## What are the logical absolutes?

The logical absolutes are the following: 1) **law of identity: “A = A”**. Or in other words, something is what it is and isn’t what it isn’t. 2) law of non contradiction- “A ≠ not-A”.

## What are the three laws of logic?

laws of thought, traditionally, the three fundamental laws of logic: **(1) the law of contradiction, (2) the law of excluded middle (or third), and (3) the principle of identity**.

## What are the four laws of logic?

The Law of Identity; 2. The Law of Contradiction; 3. The Law of Exclusion or of Excluded Middle; and, 4. The Law of Reason and Consequent, or of Sufficient Reason.”
