After a bit of reflection it occurred to me that each of the data manipulation operations reflects each of the four aspects of sanity I discussed earlier. It is almost as if being granted these operations by your mind is being granted your degree of health.
If you have select privilege you are able to focus. If you have insert privilege you are allowed flexibility. If you have update privilege you maintain objectivity. If you have delete privilege you are permitting yourself to be resilient.
It should be noted that you not only grant these privileges to yourself. You grant them to other people as well. Then the security cube can become personally relevant defining your simplicity or complexity as a person. The same goes for any system you design.
