1)  To know that a thing is a thing surely you need 
 to know what a convergent harmonic series is, otherwise you can't 
 be sure that the thing is not a convergent harmonic series
2)  We know that a thing is a thing
3)  :. Convergent harmonic series are something we all know
I feel better about my upcoming math exam already.
