Truth and Validity

When we deal with the form of deductive argument, we also deal with ‘valid’ and ‘true’, on the one hand, and ‘invalid’ and ‘false’, on the other. This particular distinction is very prominent. Only statements are true (or false) whereas only arguments are valid (or invalid). This distinction will take us to this table.

Statements        Arguments

1) True                  Valid

2) True                  Invalid

3) False                 Valid

4) False                 Invalid

This table helps us to understand the following distinction. a) A valid argument (1 and 3) may consist of completely true statements or completely false statements or both true and false statements. b) An invalid argument (2 and 4), similarly, may consist of statements in exactly the same manner mentioned above. Therefore it means that truth and validity may or may not coincide.
