Crystal-clear case for a well-ordered universe

THE logic in Fr Con McGillicuddy’s argument for a designed universe (Letters, September 17) is actually very difficult to see. There are a number of problems with his argument.

1. The four seasons are hardly indicative of a loving designer since in that case the designer must only love those people who live between the poles and the tropics.

2. It is a fallacy to claim that “where there is design, there must be a designer”. Crystals are regular and ordered, but have no designer: they grow naturally. Snowflakes are another example.
