James Allen
Discrimination

"A blind man left in a strange place may go grope his way in darkness, but not without much confusion and many painful falls and bruisings. Without discrimination a man is mentally blind, and his life is a painful groping in darkness, a confusion in which vice and virtue are indistinguishable one from the other, where facts are confounded with truths; opinions with principles, and where ideas, events, men, and things appear to be out of all relation to each other. A man's mind and life should be free from confusion. He should be prepared to meet every mental, material and spiritual difficulty, and should not be inextricably caught (as many are) in the meshes of doubt, indecision and uncertainty when troubles and so-called misfortunes come along. He should be fortified against every emergency that can come against him; but such mental preparedness and strength cannot be attained in any degree without discrimination, and discrimination can only be developed by bringing into play and constantly exercising the analytical faculty."
