The suppressed proposition is--'We must cherish whatever is the stay of virtue.' The whole syllogism then stands thus:-- We must cherish whatever is the stay of virtue, Self-respect is the stay of virtue, therefore We must cherish self-respect. Dilemma is derived from a Greek word, and signifies twice an argument. It is an argument divided into several members, and infers of each part what is to be inferred of the whole. Thus: Either we shall live or die. If we live, we can only live happily by being virtuous; and if we die, we can only die happy by being virtuous; therefore, we ought always to be virtuous. In the dilemma, question one argument at a time, as in preceding cases. The Sorites uses several middle terms by which the predicate of the last proposition is connected with the first subject. Of this argument the well-known speech of Themistocles is a specimen. 'My son,' said that eminent person, 'governs his mother, his mother governs me, I govern the Athenians, the Athenians govern Greece, Greece governs Europe, and Europe governs the world; therefore, my son governs the world.' In these instances, question each assertion, as there are as many acts of reasoning as intermediate propositions. The Onus Probandi, or Burden of Proof, is said to rest with him who would dispute any point in favour of a presumptive, or generally allowed truth. But manly logic holds no quibbling about who shall prove. Whatever he asserts, the honest reasoner should be prompt to prove.
