nals, our telegraphs, what else are they than organs of human 
language on a more extended scale? our telescopes, our micro- 
scopes, W 
extended. Thus all the inventions of our civilization tend to 
enlarge the horizon of the individual man, And this is the true 
destiny of man. o not know of a greater motto or life- 
principle than that which was written on the temple of the 
oracle of Delphi in ancient Greece: v%e ceavidy—"' Know thy- 
self;” but another is equally great, written by Wilhelm von 
Humboldt, the great pbilologist, (brother of the author of the 
osmos), it is this: “I wish to leave when dying as little as pos- 
sible behind me in this world, with what 1 have not come in 
contact,” that is what I have not mastered with my mind. Hum- 
boldt wanted the most perfect knowledge of the outer world, 
while the Greek philosopher wanted the deepest knowledge of 
himself. One of these sentiments is only the reverse of the 
other, or rather it follows immediately from the other. The 
most thorough knowledge of the outside world involves the 
deepest insight into ourselves; just as in morals, he who loves his 
neighbor the truest is the happiest, and thus loves himself the 
truest.
