WHAT is truth ? This great question has occupied 

 the more thoughtful of men for thousands of years, 

 and elicited myriads of attempts to answer it, myriads 

 of truths and untruths. Every history of philosophy 

 gives a longer or shorter account of these countless 

 efforts of the advancing mind of man to attain a clear 

 knowledge of the world and of itself. Nay, even 

 "world-wisdom" itself, or philosophy in the proper 

 sense of the word, is nothing but a connected effort to 

 unite the general results of man's investigation, ob- 

 servation, reflection, and thought, and bring them to a 

 common focus. Without prejudice and without fear, 

 philosophy would tear the mantle from "the veiled 

 statue of Sais," and attain a full vision of the truth.
