All operating systems have a philosophy. And, the philosophy of an operating system matters. What is the Linux philosophy and how does it affect the community? How has it changed software development for the ages?
Whether we know it or not, most of us have some sort of philosophy of life. It may be as simple as, "Be kind to others," or it might be a very complex life philosophy.
Many companies have some sort of philosophy as well. They may be unwritten or well-documented. When I worked at IBM, from 1974 through 1995, the IBM philosophy was well-documented and strongly ingrained in the culture. IBM's philosophy covered its business practices and how employees, customers, and suppliers were to be treated. The IBM prime directive, as it were, was to treat everyone fairly, with respect and dignity.
