The article distinguishes between the various arguments traditionally offered as justifications for the principle of academic freedom. Four main arguments are identified, three consequentialist in nature (the argument from truth, the democratic argument, the argument from autonomy), and one nonconsequentialist (a variant of the autonomy argument). The article also concentrates on the specific form these arguments must take in order to establish academic freedom as a principle distinct from the more general principles of freedom of expression and intellectual freedom.
