This work covers everything related to different psychologists who over the years have left significant contributions to the field of psychology such as Descartes, Aristotle, Locke, among others. It should be noted that many of our problems generated by our hectic daily life, having to deal with stress, fatigue, exhaustion and many pressures that the world around us gives us, motivates us to resort to Psychology as a way of relieve all these tensions, being able to help us solve the problems we have to relate to other people or solve the problems of our daily lives.
