Premises are land and buildings together considered as a property. This usage arose from property owners finding the word in their title deeds , where it originally correctly meant "the aforementioned; what this document is about", from Latin prae-missus = "placed before".
Each of the premises has one term in common with the conclusion: in a major premise, this is the major term (i.e., the predicate of the conclusion); in a minor premise, this is the minor term (i.e., the subject of the conclusion). For example: Major premise: All humans are mortal. Minor premise: All Greeks are humans.
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 ...
In this form, you start with the same first premise as with modus ponens. However, the second part of the premise is denied, leading to the conclusion that the first part of the premise should be denied as well. It is shown below in logical form. If A, then B Not B Therefore not A. [3] When modus tollens is used with actual content, it looks ...
Premise is a claim that is a reason for, or an objection against, some other claim as part of an argument. Premise (from the Latin praemissa [propositio], meaning "placed in front") may also refer to: Premises, land and buildings together considered as a property; Premise (narrative), the situational logic driving the plot in plays

Some hawkers are rich. Therefore, some men are rich. Invalid argument. This can be more easily seen by giving a counter-example with the same argument form:
In this example, the first premise is a conditional statement in which "P" is the antecedent and "Q" is the consequent. The second premise "affirms" the antecedent. The conclusion, that the consequent must be true, is deductively valid. A mixed hypothetical syllogism has four possible forms, two of which are valid, while the other two are invalid.
The form of a modus tollens argument is a mixed hypothetical syllogism, with two premises and a conclusion: If P, then Q. Not Q. Therefore, not P. The first premise is a conditional ("if-then") claim, such as P implies Q. The second premise is an assertion that Q, the consequent of the conditional claim, is not the
