Syllogism Validity Checker

made by Joshua Little

A simple tool to check the validity of categorical three statement syllogisms. This was made for fun, based off topics discussed in my intro to logic class.


Categories / Groups


Premise 1

Premise 2

Conclusion


Validity Tests: ?

  • Equal Negatives Test: ?

    The number of negative statements in the conclusion must equal the number of negatives in the premises.

  • Quantity Test: ?

    If both of the premises are particular in quantity, then the conclusion must also be particular, and if both premises are universals, then the conclusion must be universal.

  • Distributed Conclusion Test: ?

    If a group is distributed in the conclusion, then it must also be distributed in a premise.

  • Distributed Middle Group Test: ?

    The middle group must be distributed in at least one of the premises.
