A premise or premiss [a] is a proposition—a true or false declarative statement—used in an argument to prove the truth of another proposition called the conclusion. [1] Arguments consist of a set of premises and a conclusion. An argument is meaningful for its conclusion only when all of its premises are true. If one or more premises are ...
The premise of a text such as a book, film, or screenplay is the initial state of affairs that drives the plot. Most premises can be expressed very simply, and many films can be identified simply from a short sentence describing the premise.
Premises and conclusions are normally seen as propositions. A proposition is a statement that makes a claim about what is the case. In this regard, propositions act as truth-bearers: they are either true or false. [18] [19] [3] For example, the sentence "The water is boiling." expresses a proposition since it can be true or false.
A set of strings of symbols that are constructed according to specific syntactic rules, used in mathematics, computer science, and formal logic to precisely define expressions without ambiguity. formal logic The study of inference with purely formal content, where no interpretation is given to the terms and only the logical form is considered.
Deductive arguments are sometimes referred to as "truth-preserving" arguments. For example, consider the argument that because bats can fly (premise=true), and all flying creatures are birds (premise=false), therefore bats are birds (conclusion=false). If we assume the premises are true, the conclusion follows necessarily, and it is a valid ...
For example, in UK, people speak of "Crown property" meaning property belonging to the State. Similarly: "The White House had no comment to make." Minor premise – statement in an argument. Moral reasoning – reasoning employed in rhetoric that determines a conclusion based on evidence; used in issues of ethics, religion, economics, and politics.
Examples: The column-14 operator (OR), shows Addition rule: when p=T (the hypothesis selects the first two lines of the table), we see (at column-14) that p∨q=T. We can see also that, with the same premise, another conclusions are valid: columns 12, 14 and 15 are T.
Consider the modal account in terms of the argument given as an example above: All frogs are green. Kermit is a frog. Therefore, Kermit is green. The conclusion is a logical consequence of the premises because we can not imagine a possible world where (a) all frogs are green; (b) Kermit is a frog; and (c) Kermit is not green.
