The male sense of space must differ from that of the female, who has such interesting, active, and significant inner space. The space that interests men is outer. The fly ball high against the sky, the long pass spiraling overhead, the jet fighter like a scarcely visible pinpoint nozzle laying down its vapor trail at 40,000 feet, the gazelle haunch flickering just beyond arrow-reach, the uncountable stars sprinkled on their great black wheel, the horizon, the mountaintop, the quasar-these bring portents with them and awaken a sense of relation with the invisible, with the empty. The ideal male body is taut with lines of potential force, a diagram extending outward; the ideal female body curves around centers of repose.
