Truth and facts have a lot in common, but they are not exactly the same. Truth is something that is the case. Facts are true statements. Truth is best described using facts and logical reasoning.
A truth-value is a label that is given to a statement (a proposition) that denotes the relation of the statement to truth.
Mark Twain is said to have said, “If you tell the truth you don’t have to remember anything”, meaning if you tell a lie you have to remember what lie you told to who.
We explore the nature of truth, the different types of truth, and the different types of entities who report truth to better understand the nature of information.
We explain inductive reasoning, a bottom-up reasoning method that reasons by consistency, comparing particulars and probabilities to find likely truths.
We explain and compare the different types of reasoning methods including deductive, inductive, abductive, analogical, and fallacious reasoning.
We present a basic theory of human knowledge to help illustrate some essentials of “what we can know” and “how we can know it.”
