There is an inevitable conflict between one's role as a pleasant human being and one's role as a theorist. A theorist must assert the truth as clearly as possible: the deeper and more general that truth, the more forceful and all-encompassing the assertion, all the way up to universal laws based on mathematical inevitability. Unfortunately, saying a particular set of ideas is absolutely and universally true sounds arrogant to those who don't believe them yet.
Because this site represents a universal theory, not a person, the writing voice (or "authorial tone") will be assertive and impersonal, and I hope will hew as close as possible to the truth as I understand it. For a theorist, arrogance is more intellectually honest than false modesty.
