The attempt is more than commonly worthless; but as Montucla and others have referred to the verses at the end, and as the tract is of the rarest, I will quote them: Circulus loquitur.
And so both the criterion and the proof are thrown into the 117 circulus in probando, by which it is found that they are both of them untrustworthy, for as each looks for proof from the other, each is as untrustworthy as the other.
And the fifth, or the circulus in probando, arises when that which should be the proof needs to be sustained by the thing to be proved.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "circulus" in a variety of sentences. We hope that you will now be able to make sentences using this word.
