Document Summary
If you love me then you must marry me. Symbolization must be done in accordance with the principle of uniformity. One-to-one correspondence between the units of meaning symbolized and symbols replacing them. A possible symbolization of example a above is Though they are different, this symbolization could also suit arguments b and c. It is an appropriate symbolic form for showing the argument, but not how we argue or how the argument proceeds. For example, in the example c, the strategic planting of names in a sentence, or multiple sentences, is what makes the argument possible, and not the order of the sentences. So this symbolic logic is inadequate for example c. Another possible symbolization would be replacing the sentences with something else Since a is true, then b is true. Units of meaning to be symbolized are sentences. Units of meaning to be symbolized are names of categories.
