Note (return) — Chapter VII
Reading edition
2. "The Law of the Conditioned," as a ground of faith in the Infinite Being, is utterly void, meaningless, and ineffectual. Let us re-state it in Hamilton's own words: "The conditioned is the mean between two extremes, two inconditionates exclusive of each other, neither of which can be conceived as possible, but of which, on the principle of Contradiction and Excluded Middle, one must be admitted as necessary." It is scarcely needful to explain to the intelligent reader the above logical principles; that they may, however, be clearly before the mind in this connection, we state that the principle of Contradiction is this: "A thing can not at the same time be and not be; A is, A is not, are propositions which can not both be true at once." The principle of Excluded Middle is this: "A thing either is or is not--A either is or is not B; there is no medium." 354 Now, to mention the law of Excluded Middle and two contradictories with a mean between them, in the same sentence, is really astounding. "If the two contradictory extremes are equally incogitable, yet include a cogitable mean, why insist upon the necessity of accepting either extreme? This necessity of accepting one of the contradictories is wholly based upon the supposed impossibility of a mean; if a mean exists, that may be true, and both contradictories together false. But if a mean between two contradictories be both impossible and absurd, Hamilton's 'conditioned' entirely vanishes." 355 If both contradictories are equally unknown and equally unthinkable, we can not discover why, on his principles, we are bound to believe either.
