Professor: It has been argued that freedom of thought is a precondition for intellectual progress, because freedom of thought allows thinkers to pursue their ideas, regardless of whom these ideas offend, in whatever direction they lead  However, it is clear that one must mine the full implications of interrelated ideas to make intellectual progress, and for this, thinkers need intellectual discipline
