The possibility of a genuine metatheory of morality is not available. Even psychology has its ethical presuppositions. ... A metatheory of morality would be legitimate only if the existence of a hierarchy of absolute, and hence unconditioned, truths were established. They would then provide a framework of supra-ethical categories. The primary ambition of Nietzsche's critique of knowledge is to expose just such an exercise ... as sleight of hand, an efficacious deception. This critique sets out to demonstrate that ‘truths' are fictions masking moral commitments.

Fir: it contains a great deal of air and fire with very little moisture and the earthy, so that, as its natural properties are of the lighter class, it is not heavy. Hence, its consistence being naturally stiff, it does not easily bend under the load, and keeps its straightness when used in the framework. But it contains so much heat that it generates and encourages decay, which spoils it; and it also kindles fire quickly because of the air in its body, which is so open that it takes in fire and so gives out a great flame.
Vitruvius
If human beings were or had to be this or that substance, this or that destiny, no ethical experience would be possible... This does not mean, however, that humans are not, and do not have to be, something, that they are simply consigned to nothingness and therefore can freely decide whether to be or not to be, to adopt or not to adopt this or that destiny (nihilism and decisionism coincide at this point). There is in effect something that humans are and have to be, but this is not an essence nor properly a thing: It is the simple fact of one's own existence as possibility or potentiality.
Giorgio Agamben
Civil rights, as we may remember, are reducible to three primary heads; the right of personal security; the right of personal liberty; and the right of private property. In a state of slavery, the two last are wholly abolished, the person of the slave being at the absolute disposal of his master; and property, what he is incapable, in that state, either of acquiring, or holding, in his own use. Hence, it will appear how perfectly irreconcilable a state of slavery is to the principles of a democracy, which form the basis and foundation of our government.
St. George Tucker
Our failure to discern a universal good does not record any lack of insight or ingenuity, but merely demonstrates that nature contains no moral messages framed in human terms. Morality is a subject for philosophers, theologians, students of the humanities, indeed for all thinking people. The answers will not be read passively from nature; they do not, and cannot, arise from the data of science. The factual state of the world does not teach us how we, with our powers for good and evil, should alter or preserve it in the most ethical manner.
Stephen Jay Gould
My immediate consciousness, my absolute perception, cannot go beyond myself, - I have immediate knowledge only of myself, whatever I know further I know only by reasoning, in the same manner in which I have come to those conclusions concerning the original powers of Nature, which certainly do not lie within the circle of my perceptions. I, however, - that which I call myself, - am not the man-forming power of Nature, but only one of its manifestations; and only of this manifestation am I conscious, not of that power, whose existence I have only discovered from the necessity of explaining my own.
