[Petrarch said] "Everyone should write in his own style." The theme to note here is Self-Consciousness. It is allied to Individualism but it differs from it in being not a social and political condition but a mental state. One can be in prison, individuality all but submerged, and yet be acutely self-conscious. Individualism has limits imposed by the coexistence of many other individuals; Self-Consciousness has none. Over the centuries it has dug ever deeper into the ego, with no boundary in sight.
Doesn't that sound just like blogging? Well, I don't mean that it *sounds* like blogging, but that blogging is a logical activity to have emerged from this pervasive idea.
