It&#x27;s an obviously an analogy.<p>In modern society, is knowing how to change a tire more practical than understanding the basis of argument?<p>&gt; You tend to be good at the things you work at, and work at the things you like.<p>You work at those things which bring you utility. It&#x27;s a subtle difference, but utility includes activities you don&#x27;t like but which generate income. Ideally, those activities are also beneficial for society. Critical thinking is more highly valued in modern society than is knowing how to change a flat.
