“Aristotle says the infinite is imperfect, unfinished, and therefore unthinkable; it is formless and confused. Only as objects are delimited and distinct do they have a nature.”

Context: When a man achieves a fair measure of harmony within himself and his family circle, he achieves peace; and a nation made up of such individuals and groups is a happy nation. As the harmony of a star in its course is expressed by rhythm and grace, so the harmony of a man's life-course is expressed by happiness; this, I believe, is the prime desire of mankind.
"The universe is an almost untouched reservoir of significance and value," and man need not be discouraged because he cannot fathom it. His view of life is no more than a flash in time. The details and distractions are infinite. It is only natural, therefore, that we should never see the picture whole. But the universal goal — the attainment of harmony — is apparent. The very act of perceiving this goal and striving constantly toward it does much in itself to bring us closer, and therefore, becomes an end in itself.

Context: An unjust composition never fails to contain error and falsehood. Therefore an unjust connection of ideas is not derived from nature, but from the imperfect composition of man. Misconnection of ideas is the same as misjudging, and has no positive existence, being merely a creature of the imagination; but nature and truth are real and uniform; and the rational mind by reasoning, discerns the uniformity, and is thereby enabled to make a just composition of ideas, which will stand the test of truth. But the fantastical illuminations of the credulous and superstitious part of mankind, proceed from weakness, and as far as they take place in the world subvert the religion of REASON, NATURE and TRUTH.
