GENERAL SUMMARY

have a fairly sensitive conscience. But whatever ren- 
ders the imagination of men more vivid and strengthens 
the habit of recalling and comparing past impressions, 
will make the conscience more sensitive, and may even

advancement of morality. Ultimately man no longer 
accepts the praise or blame of his fellows as his chief 
guide, though few escape this influence, but his habi-

seems to be universal; and apparently follows from a
