Plato assassinated his teacher, Socrates, by writing down conversations the Socrates allegedly engaged in. In the conversations, Socrates routinely traps his opponents by asking them to choose between two equally plausible alternatives (one of which must be rejected on the basis of some principle). His either/or logic obscures that there is generally an unmentioned third choice that, if mentioned, would cause the entire edifice of Socrates' argument to collapse upon itself.
