Problem: This is not to say that Whitehead's thought was widely accepted or even well-understood. His philosophical work is generally considered to be among the most difficult to understand in all of the western canon. Even professional philosophers struggled to follow Whitehead's writings. One famous story illustrating the level of difficulty of Whitehead's philosophy centers around the delivery of Whitehead's Gifford lectures in 192728 following Arthur Eddington's lectures of the year previous which Whitehead would later publish as Process and Reality:
Following Arthur Eddington's lectures, what did Whitehead publish?

Problem: The development of the Bronx is directly connected to its strategic location between New England and New York (Manhattan). Control over the bridges across the Harlem River plagued the period of British colonial rule. Kingsbridge, built in 1693 where Broadway reached the Spuyten Duyvil Creek, was a possession of Frederick Philipse, lord of Philipse Manor. The tolls were resented by local farmers on both sides of the creek. In 1759, the farmers led by Jacobus Dyckman and Benjamin Palmer built a "free bridge" across the Harlem River which led to the abandonment of tolls altogether.
When was Kingsbridge built?
The answer is the following:
1693
