It is curious to observe what different ideals of happiness people cherish, and in what singular places they look for this well-spring of their life. Many look for it in the hoarding of riches, some in the pride of power, and others in the achievements of art and literature; a few seek it in the exploration of their own minds, or in search for knowledge.
