Question and answer
Q: How did the Greeks use deductive reasoning ?
A: Deductive reasoning, also called deductive logic, is reasoning which constructs or evaluates deductive arguments. Deductive arguments are attempts to show that a conclusion necessarily follows from a set of premises or hypotheses. [ A deductive argument is valid if the conclusion does follow necessarily from the premises, i.e., if the conclusion must be true provided that the premises are true.
A deductive argument is sound if it is valid and its premises are true. Deductive arguments are valid or invalid, sound or unsound. Deductive reasoning is a method of gaining knowledge. An example of a deductive argument: All men are mortal Socrates is a man Therefore, Socrates is mortal The first premise states that all objects classified as "men" have the attribute "mortal". The second premise states that "Socrates" is classified as a man ? a member of the set "men". The conclusion states that "Socrates" must be mortal because he inherits this attribute from his classification as a man. ]
