Non-operational ideas are non-behavioral and subversive. The movement of thought is stopped at barriers which appear as the limits of Reason itself. - Herbert Marcuse

This organization of functional discourse is of vital importance; it serves as a vehicle of coordination and subordination. The unified, functional language is an irreconcilably anti-critical and anti-dialectical language. In it, operational and behavioral rationality absorbs the transcendent, negative, oppositional elements of Reason.

Can the human appropriation of nature ever achieve the elimination of violence, cruelty, and brutality in the daily sacrifice of animal life for the physical reproduction of the human race? To treat nature "for its own sake" sounds good, but it is certainly not for the sake of the animal to be eaten, nor probably for the sake of the plant. The end of this war, the perfect peace in the animal world — this idea belongs to the Orphic myth, not to any conceivable historical reality. In the face of the suffering inflicted by man on man, it seems terribly "premature" to campaign for universal vegetarianism or synthetic foodstuffs; as the world is, priority must be on human solidarity among human beings. And yet, no free society is imaginable which does not, under its "regulative idea of reason," make the concerted effort to reduce consistently the suffering which man imposes on the animal world.

Sociology does not ‘negate’ philosophy, in the sense of taking over the hidden content of philosophy and carrying it into social theory and practice, but sets itself up as a realm apart from philosophy, with a province and truth of its own. Comte is rightly held to be the inaugurator of this separation between philosophy and sociology. P. 375
