Baley tries to tell himself that being in the open is natural; men had
done it all their lives, and the Spacers did it now. "There is no real harm in wall-lessness." But reason alone is not enough. "Something above and beyond reason cried out for walls and would have none of space." Daneel, however, anticipates Baley's neurosis and arranges for an airtube, commonly used in space between vessels, to be connected to a ground-transport vehicle. Daneel speaks of Baley's "peculiarities," a term Baley doesn't like. He resents Daneel's concern about his neurosis and feels "a sudden need to see," motivated partly by Daneel's oversolicitude and partly by Minnim's instructions to observe. But Daneel will not retract the top of the vehicle for fear of the harm that Baley might suffer. Baley has to trick the robot driver into opening the top and exposing him to Solaria's naked sun: "Blue, green, air, noise, motion and over it all, beating down, furiously, relentlessly, frighteningly, was the white light that came from a ball in the sky.'' Daneel has to pull Baley down to keep him from injuring his eyes by staring too long at the sun, and Baley loses consciousness.
