A central feature of normal human conversations is the re-identification of individuals. It would not be a normal human conversation if a bunch of blindfolded people sat around wearing headphones and microphones, with the speech from the microphones being fed into a voice disguiser which reduced all the voices to one, and with no one identifying herself. A normal conversation requires constancy of interlocutors. The re-identification of individuals is what makes dialectical accountability possible. Moreover, through conversation, one ideally becomes friends. But friendship requires individuation.
Consequently, I am disallowing anonymous comments on this blog as of immediately. I might reconsider given good reason.
I should note that I have benefited significantly in the past from anonymous comments, and I hoping that persons now commenting anonymously will post under their real names or, at least, under a nom de plume.
I do, in fact, also believe pseudonymity is something unfortunate. Our actions and words express us: it is unfortunate if we do not openly stand behind them. I think there is a strong presumption against pseudonymity (cf. this post of mine). If you feel that the alternative to participating pseudonymously is not participating at all, I ask that you examine carefully why it is that you are unwilling to stand publicly behind one's views. This examination might yield one of three conclusions: (a) one should speak publicly in one's own name; (b) one should be silent; or (c) genuine prudence forces one into psuedonymity. I fully understand that, for instance, persons living in totalitarian regimes, graduate students and untenured faculty, etc. can have very good prudential reasons for participating only pseudonymously in discussion, and so I am not banning pseudonymous participation.
In fact, I strongly advise graduate students and untenured faculty to post only pseudonymously, unless they have good reason to believe the prudential concerns do not apply to them. (I should also note that if one is in a category where one's life or liberty depends on not being identified, it might be wiser not to post even pseudonymously unless you use appropriate independent encryption-based services to access the Internet, since there may still be ways of being tracked down.)
Whether one falls in a category where pseudonymity is justified is a judgment one must leave to the individual prudence of the phronimos.
Nonetheless, I do ask that if you use a pseudonym, you try to stick to one pseudonym. This will make possible the re-identification of conversation partners. I can, however, understand that you might on rare occasions switch to a new pseudonym (e.g., if one's cover has been blown, or one has lost access to an account).
