"The way you came out ... is the way you go in."

Although ostensibly a casual reference to how his son sometimes exits and enters home -- by a secret ladder of iron rungs on the outer wall of the house -- this remark of Mr. Halloway’s is reminiscent of sayings of the pre-Socratic Greek philosopher Heraclitus of Ephesus (c. 535 – c. 475 BCE), sometimes referred to as “the weeping philosopher.” The painting of Heraclitus shown here is by the Dutch Renaissance painter Hendrick ter Brugghen (1588-1629).

Characteristic sayings of Heraclitus include “The road up and the road down are the same road” and “The beginning and the end are the same.” The sad and lonely character of Heraclitus and his philosophy seem to describe the life and outlook of Mr. Halloway as well.
