Many things in the common law have been introduced, for the public good, which are inconsistent with abstract reasoning.

Explanation

The common law is practical, not theoretical — it sometimes adopts rules that serve the public good even when pure logic might point elsewhere.

Where this applies

• A common law rule seems illogical in theory but works well in practice.
• Someone argues that a longstanding legal rule should be abolished because it does not follow pure logic.
