American Old-time song lyrics from www.traditionalmusic.co.uk 
Let Each Man Learn to Know Himself. 
Let each man learn to know himself, To gain that knowledge let him labor; To improve those failings in himself, That he condemns so in his neighbor How leniently our faults we view. And guilty conscience strive to smother; And yet how harshly we review Those self-same failings in another. 
Chorus. Let each man learn to know himself, To gain that knowledge let him labor; To improve those failings in himself, That he condemns so in his neighbor. 
If you should meet an erring one, Whose deeds are blamable and thoughtless, Consider, ere you cast the stone, That you yourself are free and faultless. Oh! list to that small voice within, Whose whisperings oft make men confounded; And trumpet not another's sin, Lest you should blush if you were sounded.-Chor. 
If in self-judgment you should find,] That you to others are superior; Think Providence to you's been kind. As you should be to your inferior. Example sheds a genial ray, Which oft-times men are apt to follow; First learn to improve yourself to-day, And then improve your friend to-morrow.-Chorus,
