If so, the argument is strong. The form of argument can be shown by the use of symbols. A statement form can be shown to be a logical truth by either a showing that it is a tautology or b by means of a proof procedure. Horn stimulated widespread interest in argument mapping.
The validity of an argument is not a guarantee of the truth of its conclusion.
How argument mapping helps with critical thinking[ edit ] This section needs additional citations for verification. He also introduced terminology that is still current describing convergent, divergent and serial arguments. What is the philosopher trying to show must be true? Socrates is a man, all men are mortal therefore Socrates is mortal is clearly an argument a valid one at thatbecause it is clear it is asserted that Socrates is mortal follows from the preceding statements.

If an argument is valid, it is a valid deduction, and if its premises are true, the conclusion must be true: There is no consensus as to whether the conclusion should be at the top of the tree with the reasons leading up to it or whether it should be at the bottom with the reasons leading down to it.
