Paul Campos is blunt:
Our modal law professor is a man or woman who knows very little about the actual practice of law in any form, given that he or she spent very little time — increasingly, at more elite schools, literally no time — practicing law before entering the legal academy. This fact means that to a significant extent the leaders of our profession (let us call our hypothetical specimen Professor Leader) have to spend much of their time in class bullshitting. This is a natural consequence of the fact that the rhetorical posture of Prof. Leader requires him to represent to his students that is teaching them how to be lawyers. But Prof. Leader knows nothing about being a lawyer. Hence, he must bullshit — he does not lie to his students about how to be a lawyer (doing so would require him to know how to be a lawyer, while attempting to deceive his students regarding the substance of that knowledge); rather, he "talks without knowing what he is talking about."
