Today we begin Part II – The three dimensions of the human person. The anthropological model used in this text presents the human person in three dimensions: the biological, the emotional or psychological and the spiritual dimension. The three are distinct, yet work together to bring about the overall good of the human person. In fact, there are tendencies or inclinations on each of these levels that orient the human person from within to his end. To introduce part two, along with presenting the model anew, the text discusses the important notion of natural inclinations and how it is used in this book.
