The people of today value utility above all. If something works (makes you happy), then it must be right. Feelings are their first and last, their everything. Yet they have the gall to appeal to reason to support their folly! This shows their belief in feelings is not so strong after all. Who can take them seriously now? They, who totally compromise their philosophy of wickedness by trying to support it with reason.
They have built a straw house on sand, and now cleverly enclose it in cardboard - to make it all the more permanent.
