I fear that most of our lives are self-defined by what happens on the surface, when in fact they are truly defined by how we interpret what is happening on the surface.
It may be easier to understand this if we think of a computer with its operating system, its applications and its output. A computer is not identical to its output. Indeed, the output is dependent upon the application, and the application is dependent upon the operating system.
Most of us spend our lives searching for new applications and working to achieve new outputs. But we fail to address the fundamental issue: our operating system. Philosophy challenges my personal operating system.
