The System has two aspects. The scientific one explains the how: the mechanisms, techniques, and tools on which operations are based. Marketing, for example, is a business sector, but it is also the science of selling, which studies how buyers behave, between rationality and the unconscious.
The philosophical one explains the why, and from there the rest follows, because the scientific is the engineering consequence of the philosophical.
When we talk about soul and spirit, we are talking about philosophy.
The philosophical part of the System explains the why of the laws and rules that bind man in his activities, not only entrepreneurial ones. In fact, the philosophical part of the System explains the why of the political sciences on which the institutional and governmental systems of the whole world are founded. Because yes, all the institutional systems of all the countries of the world are aligned with the concepts and principles of human nature.
The philosophical aspect of the System is the one in which there are the answers to who we are and where we are headed, answers that make us understand the sense and meaning of man's life, on which he has built the System.
Understanding the philosophical aspect of the System leads man to live life to the fullest.
