Person centred psychology developed from the work of Carl Rogers, an American psychotherapist and psychologist, who died in 1987. Over the last 50 years the Person Centred Approach (PCA)has become one of the most influential approaches to understanding and helping people. Its theory and philosophy, originally developed in the field of counselling and psychotherapy, has been extended to include applications to education, social and community work and the exploration of interpersonal and international conflict. This book poses a series of everyday questions, such as, What makes us tick? Where do my values come from? How did I become who I am? Why are relationships so important? and then explores each of these issues showing how and why person centred psychology takes an optimistic view of human nature. In the process it also provides some novel ideas to help us explain why people behave in the way they do.
