I present a general and personal view of the various aspects in which Man is and should be studied. The main problem lies in the lack of a fully accepted definitions of consciousness and ‘normal’ state of consciousness. The concepts of personality and consciousness are discussed. The most important issues in the study of consciousness are highlighted. The concepts of the field of consciousness and bandwidth are presented and discussed in relation with memory recovery and the processing capacity of the brain. The similarities and differences of consciousness, mind, and psyche are listed. The mind-brain problem is presented, and the many possible relationships are defined and commented. We highlighted some new topics such as the need and importance of being able to access all stored memories to become a more ‘complete’ Homo sapiens. Some possible non-physical components are briefly mentioned.
