One of the few things I remember from my freshman philosophy class is learning about the syllogism. The syllogism is a logical tool used to deduce a conclusion from a major and minor premise (for example: A: All students wear red. B: John is a student. C: Therefore, John wears red). You’ve probably seen it before, but have you seen it used as a formula for holy living?
The Puritan theologian William Ames (1576–1633) believed that the syllogism—when used rightly—offered considerable moral guidance, for it contained the “force and nature of conscience (I.3).” Ames defined the human conscience as “man’s judgment of himself, according to the judgment of God of him (I.1).” The syllogism provided the means for the conscience’s operation of accusing, excusing, and comforting the moral agent. It consists of three elements:
- The Proposition: The proposition fulfills the role of the major premise. The Latin term Ames employed is synteresis, meaning a source for principles of moral action.Ames also referred to the proposition as a “light” and a “law.” God’s will and commandments furnish this “storehouse of principles.” While nature can often lead men and women in moral living, God’s revealed will is the only perfect rule of conscience, illuminating mankind’s moral duty (I.4–7).
- The Witness: the witness, which Ames also termed the “index,” “book,” “review,” or “assumption,” functions as the minor proposition. The witness is a subjective statement about the self for the purpose of considering one’s moral condition in reference to the proposition. It measures the moral agent alongside the law. The moral state of the human will is compared with the standard of God’s will (I.21–25).
- The Conclusion: the conclusion, also referred to as the “judgment,” derives partly from the proposition and partly from the witness. In the conclusion, “God’s commandment and man’s fact are mutually joined together.” The conclusion passes the sentence, or “application,” of either comfort or condemnation for the man or woman in light of the major and minor premises (I.28–32).
In sum, “in the Proposition God’s Law is declared, and in the Assumption, the fact or condition of man is examined, according to that Law; so in the Conclusion, the sentence concerning man is pronounced according to his fact…by virtue of the Law that hath been declared” (I.28).
Ames provides two examples. The first delivers accusation but the second comfort:
1. [A] “He that lives in sin, shall die” [B] “I live in sin” [C] “Therefore, I shall die”
2. [A] “Whoever believes in Christ, shall not die but live” [B] “I believe in Christ” [C] “Therefore, I shall not die but live (I.3)”
For Ames, the objective of the syllogism was to assist men and women in assessing their moral condition in light of God’s commandments and in conforming their wills to God’s will. Ultimately, it shows us how desperately short we fall, pointing to our need to rest faith in the Christ who followed God’s will perfectly.
