Discrete logic is a term that refers to logic circuits that are made almost entirely of discrete logic chips such as AND and ORs (or their complements NAND and NORs).... continue reading ›
When a transistor is on, or open, then an electric current can flow through. And when it's off, then no current flows. When you string a bunch of these transistors together, then you get what's called a logic gate, which lets you add, subtract, multiply, and divide binary numbers in any way imaginable.... read more ›

“Is "logical" always "true"?” Not necessarily. Logic is a system for evaluating the truth of a statement based on the idea that the *premise* is true. Your logic could be flawless, but if it's based on an untrue premise, then it's false.... continue reading ›
Logic is a formal system of analysis that helps writers invent, demonstrate, and prove arguments. It works by testing propositions against one another to determine their accuracy.... read more ›
formal logic, the abstract study of propositions, statements, or assertively used sentences and of deductive arguments. The discipline abstracts from the content of these elements the structures or logical forms that they embody.... see details ›
The conjunction of the statements P and Q is the statement “P and Q” and its denoted by P∧Q. The statement P∧Q is true only when both P and Q are true. The disjunction of the statements P and Q is the statement “P or Q” and its denoted by P∨Q. The statement P∨Q is true only when at least one of P or Q is true.... continue reading ›
Mathematicians use logic all the time to prove theorems and other mathematical facts. Everything we know about math right now is based off of these logical proofs. Without these, we wouldn't have our formulas, like the wonderful quadratic formula or the very useful Pythagorean Theorem.... see details ›
Basic Mathematical logics are a negation, conjunction, and disjunction. The symbolic form of mathematical logic is, '~' for negation '^' for conjunction and ' v ' for disjunction. In this article, we will discuss the basic Mathematical logic with the truth table and examples.... see more ›
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”. Or in other words, something is not what it is not.... see details ›

Logic is an attribute of God. God is not subject to logic in the sense that he is beneath it, nor is logic an "invention" of God. God is always utterly logical, because logic is part of who he is. Logic is the set of rules we must follow to think like God thinks, which is to think rightly.... continue reading ›

A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.... read more ›
As the father of western logic, Aristotle was the first to develop a formal system for reasoning. He observed that the deductive validity of any argument can be determined by its structure rather than its content, for example, in the syllogism: All men are mortal; Socrates is a man; therefore, Socrates is mortal.... see details ›
Four types of reasoning will be our focus here: deductive reasoning, inductive reasoning, abductive reasoning and reasoning by analogy.... see more ›
There are three stages to creating a logical argument: Premise, inference, and conclusion. The premise defines the evidence, or the reasons, that exist for proving your statement. Premises often start with words like “because”, “since”, “obviously” and so on.... view details ›
Logic may be divided according to the three acts of the intellect:

There are five logical operator symbols: tilde, dot, wedge, horseshoe, and triple bar. Tilde is the symbol for negation.... see more ›
The systematic study of logic seems to have been undertaken first by Aristotle. Although Plato used dialectic as both a method of reasoning and a means of philosophical training, Aristotle established a system of rules and strategies for such reasoning.... view details ›
Both Plato and Aristotle conceived of logic as the study of argument and from a concern with the correctness of argumentation. Aristotle produced six works on logic, known collectively as the "Organon", the first of these, the "Prior Analytics", being the first explicit work in formal logic.... see more ›
