Reason spoiled, marred, or robbed of its perfection, ceaseth to be rational, and should not be called reason; inasmuch as it is premised to be depraved, or degenerated from a rational nature; and in consequence of the deprivation of its nature, should also be deprived of its name, and called subterfuge, or some such like name, which might better define its real character. Those who invalidate reason, ought seriously to consider, "whether they argue against reason, with or without reason; if with reason, then they establish the principle, that they are laboring to dethrone;" but if they argue without reason, (which, in order to be consistent with themselves, they must do,) they are out of the reach of rational conviction, nor do they deserve a rational argument.

The free movement of the moral impulse to establish justice for animals generally and the claim of their rights from mankind are hidden in a natural psychic sensibility in the deeper layers of the Torah. In the ancient value system of humanity ... the moral sense had risen to a point of demanding justice for animals. ... Just as the democratic aspiration will reach outward through the general intellectual and moral perfection ... so will the hidden yearning to act justly towards animals emerge at the proper time. What prepares the ground for this state is the commandments, those intended specifically for this area of concern. There is indeed a hidden reprimand between the lines of the Torah in the sanction to eat meat.

Or, to go a step further, let us glance at what science has done to establish rational foundations for physical and moral health. Science tells us how we ought to live in order to preserve the health of our own bodies, how to maintain in good conditions of existence the crowded masses of our population. But does not all the vast amount of work done in these two directions remain a dead letter in our books? We know it does. And why? Because science today exists only for a handful of privileged persons, because social inequality which divides society into two classes - the wage-slaves and the grabbers of capital - renders all its teachings as to the conditions of a rational existence only the bitterest irony to nine-tenths of mankind.

It is not possible, I think, to rise from the perusal of the arguments of Clark and Spinoza without a deep conviction of the futility of all endeavors to establish, entirely à priori, the existence of an Infinite Being, His attributes, and His relation to the universe. The fundamental principle of all such speculations, viz. that whatever we can clearly conceive, must exist, fails to accomplish its end, even when its truth is admitted. For how shall the finite comprehend the infinite? Yet must the possibility of such conception be granted, and in something more than the sense of a mere withdrawal of the limits of phænomal existence, before any solid ground can be established for the knowledge, à priori, of things infinite and eternal.
George Boole
Consider what kind of authority [can be ascribed to] any principle which it open to us to choose to regard as authoritative or not. I may choose for example to observe a regimen of asceticism and fasting ... for reasons of health ... What authority such principles possess derives from the reasons for my choice. Insofar as they are good reasons, the principles have corresponding authority; insofar as they are not, the principles are to that same extent deprived of authority. It would follow that a principle for the choice of which no reasons could be given would be a principle devoid of authority. I might indeed adopt such a principle from whim or caprice or from some arbitrary purpose ... but if I then chose to abandon the principle whenever it suited me, I would be entirely free to do so.

I've always doubted that the socialists had a leg to stand on intellectually. They have improved their argument somehow, but once you begin to understand that prices are an instrument of communication and guidance which embody more information than we directly have, the whole idea that you can bring about the same order based on the division of labor by simple direction falls to the ground. Similarly, the idea [that] you can arrange for distributions of incomes which correspond to some conception of merit or need. If you need prices, including the prices of labor, to direct people to go where they are needed, you cannot have another distribution except the one from the market principle. I think that intellectually there is just nothing left of socialism.
