 from their value, since, to the finite mind, the infinite 

 is incomprehensible. The race has developed certain

 the storm and stress of conflicting opinion since man 

 began to think, must possess some fitness to supply a 

 natural need of man. Educational theories, too, are 

 subject to the same law of selection. Progress results, 

 not by destroying the old, but by the new additions 

 that issue from it.

Shut thee from heaven with a dome more vast, 



Till thou at length art free, 

 Leaving thine outgrown shell by life's unresting sea!
