Sinopsis

Excerpt from Outlines of Logic: An English Translation of Trendelenburg's Elementa

It is very evident that the universal proposition is supe rior to the particular; for of the two propositions, when we know the former, we are acquainted with the latter also, and know it virtually, or in potentiality. As, for instance, if a man knows that every triangle contains angles equal to two right-angles, he may be said to know that the angles of an isosceles triangle are equal to two right-angles, even if he does not know the isosceles as a form of triangle. On the other hand, a man acquainted with the particular pro position has no knowledge whatever of the universal, either virtually or actually. Again, the universal proposition is cognised by the reason, the particular by the senses.
