We always may be sure that every man-made thing arises from a problem as a purposeful solution. - George Kubler

The universe has a finite velocity which limits not only the spread of its events, but also the speed of our perceptions. The moment of actuality slips too fast by the slow, coarse net of our senses.

Actuality is when the lighthouse is dark between flashes: it is the instant between the ticks of the watch: it is a void interval slipping forever through time: the rupture between past and future: the gap at the poles of the revolving magnetic field, infinitesimally small but ultimately real. It is the interchronic pause when nothing is happening. It is the void between events.

I was surprised, while preparing this lecture, to notice how, among my friends who had read the book, a division into two groups appeared. Both groups are equally discerning and educated, and as far as I can tell, equal in numbers. One group is eager to say that they don't understand a word of it, and there are artists and historians among them. Those of the other group claim that they understood it all on first reading, without difficulty. Of course I believe them both, without understanding the combination that separates them so sharply. Perhaps distinctive and contrasting features in the comprehension of works of art are responsible. What I say speaks to some, but not to others. Some are ready, and others are not. But when both someday find that they agree in understanding it, that day may be its last as a book alive in the dissension over its intelligibility.
