Chapter 36 <Do you want to sign and seal at the same time>

A certain comrade received a remittance slip, and the reverse side of the remittance slip stated that when the payee withdraws money against the slip, he must sign or seal it in addition to the official seal of the unit where he works.This comrade did not have a private seal, but only signed his name on the remittance slip. When I went to the post office to withdraw money, I didn't know that the salesperson refused to pay, and the person who made the money had to sign and stamp it. As a result, a fierce dispute arose between the two parties.Who are the two parties in the dispute? Logically, the signature or seal of the payee is a compatible choice.The logical nature of the compatible-alternative judgment is that it is false only when all the alternatives are false, and it is true when all the alternatives are true or one of the alternatives is true.According to the logical feature of compatible selection, the payee can withdraw money as long as one of the conditions is met, that is, only sign but not stamp, or only stamp but not sign.Since the salesperson comrade did not understand the exact meaning of signature or seal, he made an illogical request to the cashier.

In fact, he regards or as a sum, and or as an and.From the perspective of logic, the payee's signature or seal and the payee's signature and seal are two different types of judgments.The former is called selective judgment, as long as one of its limbs is true, the judgment is true; the latter is called joint judgment, and it is true only if all the limbs are true.Apparently, the salesperson took the judgment of the selected words as the judgment of the joint words, and made a logical error of confusing propositions.
