But holding the balance is difficult. McHarg's use of the overlay method, while not resolving this thorny issue, was a forerunner to later forms of complex analysis in multi-criteria route evaluation and decision making. As I see it, most twentieth century landscape architects neglected the sciences and Ian McHargs overlay method neglected human culture and the arts. The technique consists of the overlapping of different thematic maps.

Lest this statement be construed as anti-religion, he cites Paul Tillich (Protestantism), Gustav Weigel (Catholicism), and Abram Heschel (Judaism) as noted religious scholars who are also in agreement with him on this point.
