xvi INTRODUCTION . Nor can she ever afford to do without it. Says Mr. Abercrombie , in his Ceremonial Ode, intended for a University , This , then , is yours : to build exultingly High , and yet more high , The knowledgeable towers . . . That so Man 's mind , not conquered by his clay , May sit above his fate , Inhabiting the purpose of the stars And trade with his Eternity . Now , in historical fact , such traffic uplifted on knowledge has hitherto been mainly conducted for Man by poetry and philosophy ; and in Man 's experience of the two , the commerce of poetry has brought the more durable profit .
