Beer]] - Full Title: The Life and Teaching of Karl Marx - Category: #books ## Highlights - From this law of thought follows directly the third, viz., the Principle of the Excluded Middle. A thing is either A or non-A; there is no middle term. Or, according to our example, the earth is either a solid body, or, if it is not solid, it is no earth; there is no middle term. The State is either monarchical, or, if it is not monarchical, it is no State. Capitalism is either oppressive, or altogether not Capitalism. Socialism is either revolutionary, or not Socialism at all; there is no middle term. (Socialism is either reformist, or not Socialism at all; there is no middle term.)
