"Who is, in the classical conception, the subject that comprehends the ontological condition of truth and untruth? It is the master of pure contemplation (theoria), and the master of a practice guided by theoria, i.e., the philosopher-statesman. To be sure, the truth which he knows and expounds is potentially accessible to everyone. Led by the philosopher, the slave in Plato’s Meno is capable of grasping the truth of a geometrical axiom, i.e., a truth beyond change and corruption. But since truth is a state of Being as well as of thought, and since the latter is the expression and manifestation of the former, access to truth remains mere potentiality as long as it is not living in and with the truth. And this mode of existence is closed to the slave — and to anyone who has to spend his life procuring the necessities of life. Consequently, if men no longer had to spend their lives in the realm of necessity, truth and a true human existence would be in a strict and real sense universal. Philosophy envisages the equality of man but, at the same time, it submits to the factual denial of equality. For in the given reality, procurement of the necessities is the life-long job of the majority, and the necessities have to be procured and served so that truth (which is freedom from material necessities) can be. Here, the historical barrier arrests and distorts the quest for truth; the societal division of labor obtains the dignity of an ontological condition. If truth presupposes freedom from toil, and if this freedom is, in the social reality, the prerogative of a minority, then the reality allows such a truth only in approximation and for a privileged group. This state of affairs contradicts the universal character of truth, which defines and “prescribes” not only a theoretical goal, but the best life of man qua man, with respect to the essence of man. For philosophy, the contradiction is insoluble, or else it does not appear as a contradiction because it is the structure of the slave or serf society which this philosophy does not transcend. Thus it leaves history behind, unmastered, and elevates truth safely above the historical reality. There, truth is reserved intact, not as an achievement of heaven or in heaven, but as an achievement of thought — intact because its very notion expresses the insight that those who devote their lives to earning a living are incapable of living a human existence."
