Compare with
unlogisch vs irrational
irrational
Unlogisch is appropriate when a line of thought contradicts the rules of logic or contains a contradiction. Irrational is broader and describes something that cannot be understood through reason. An irrational thought can therefore also be illogical, but it does not have to contain a clear logical error.
unlogisch
Der Gedankengang ist unlogisch, weil sich seine beiden Aussagen widersprechen.
The line of reasoning is illogical because its two statements contradict each other.
irrational
Der Gedankengang wirkt irrational, weil er trotz aller Fakten nur von Angst bestimmt wird.
The line of reasoning seems irrational because, despite all the facts, it is driven solely by fear.
