Three areas of knowledge hold the keys to accessing all the happiness and fulfillment possible to the individual. These are philosophy, psychology and neuroscience. Broadly speaking (with the understanding that there are overlaps between the three), philosophy furnishes the individual with answers to questions concerning how to live well, psychology provides him with explanations of why he acts and thinks the way he does, and neuroscience shows what the physical causes of consciousness and unconsciousness are.
To have even a rudimentary understanding of these three fields of knowledge is to come closer to achieving that often elusive joy and contentment which are the rewards of self-knowledge. When a person is more aware of the how, why and what of his mind and all its facets including his character, beliefs, preferences and consequent actions, he assumes greater control of the direction and form that his unique life takes. Such knowledge is empowering, as empowering as sight restored to the blind.
