rhyme or reason

Order or sense

Rhyme or reason refers to logical sense or rational explanation, almost always in negative constructions: There's no rhyme or reason to these regulations, I can't find any rhyme or reason in his behavior.

The phrase suggests that something lacks both aesthetic pattern (rhyme) and logical basis (reason)—it's simply inexplicable or arbitrary.
