Natural selection of moral values.
Following to the concept of natural selection applying to the humanity one can state that moral principles of any existing society are not in antagonistic contradiction to its survival up to this point. A trivial criterion of good and evil is an existence of the object. Specifically to the moral values these that help an existing of society are good, these lead to distraction tendencies are bad. As simple as that. Boring. Exciting, as soon we will talk about any specific moral norm.
What is time?
The best definition I have found on web is "time is the continuum of experience in which events pass from the future through the present to the past" It's very poetic and permits nice analogy with movie where one cadre follows others in equal intervals of time. Wait a moment. We are using for description of time a intervals of time. The subject can't be described from itself. Time cannot be defined other then from itself. A paradox these are legion when we a talking about time.
