Syllogistic Logic is a form of logic where conclusions are inferred from two premises. This is easier to understand with examples. I will have to note that this type of logic is rather narrow in scope and archaic. It can form logical arguments but other forms of more modern logic often supersede this. Still it is good to have a familiarity with it.

Syllogistic Examples

Dog Syllogism

Premise: All dogs are carnivorous

Premise: Pugs are dogs

Conclusion: Therefore all pugs are carnivorous

Fish Syllogism

Premise: Fish need water to breathe

Premise: Fish use gills for breathing

Conclusion: Gills use water for breathing
