Logical consistency: A set of sentences is logically consistent if and only if it is possible for all the members of that set to be true. Logical entailment: A set of sentences logically entails a sentence if and only if it is impossible for the members of the set to be true and that sentence to be false. logic symbolic-logic Share In logic, it is a fundamental law- the law of non contradiction- that a statement and its denial cannot both be true at the same time. Here are some simple examples of contradictions. 1. I love you and I don't love you. 2. Butch is married to Barb but Barb is not married to Butch. 3. In Logic, we are usually more interested in properties and relationships of sentences that hold across all truth assignments. We begin this chapter with a look at logical properties of individual sentences (as opposed to relationships among sentences) - validity, contingency, and unsatisfiability. Consistency In classical deductive logic, a consistent theory is one that does not lead to a logical contradiction. [1] The lack of contradiction can be defined in either semantic or syntactic terms.

Theories Being Logical and Consistent vs. Being an Example 5 minutes Being logical and consistent and leading by example are concepts that are similar, yet different. In this article, discover the difference between them. Being logical and consistent could be conceived as personality traits. Explain the connections among consistency, logical truth, and logical contradiction. 8-4. By examining your results from exercise 7-4(a) through (k), determine which pairs of sentences are logically equivalent and which are not. This is more than an exercise in mechanically applying the test for logical equivalence. For each pair of sentences. i) Test for a Finite Set of Inconsistent Sentences. j) Logical Equivalence of Predicate Logic Sentences. k) Test for Logical Equivalence. 6.3: Logical Truth, Contradictions, Inconsistency, and Logical Equivalence is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts. Logic is concerned with the consistency of sets of sentences (used to represent beliefs) and with consistent outcomes to processing logical formulae containing operands and operatives. A set of sentences is said to be consistent if and only if there is at least one possible situation in which they are all true. So, the following set of.

Bridge principles A consistent set of sentences is a set all of which can be true together -- or, as logicians are fond of saying: there is some possible world in which they are all true. This is not the same as saying that they all true, merely that it is that this be so. No, they are consistent. You can image a situation in which they are both true. If you were to change "Almost everyone" to "Everyone," then they'd be inconsistent. The notion of logical inconsistency can get more complicated. These two statements can be said to both logically consistent and logically inconsistent: Everybody left the room. No, they are consistent.

Coherentism is a theory of epistemic justification. It implies that for a belief to be justified it must belong to a coherent system of beliefs. For a system of beliefs to be coherent, the beliefs that make up that system must "cohere" with one another. Typically, this coherence is taken to involve three components: logical consistency. As with logical equivalence and logical entailment, we can use the truth table method to determine logical consistency. The following truth table shows all truth assignments for the propositional constants in the examples just mentioned. The third column shows the truth values for the first sentence; the fourth column shows the truth values for.
