Relativity of Ethics

Two postulates formulated the theory of special relativity.

  1. The physical law is the same in all inertial frames.
  2. The speed of light is constant in all inertial frames.

Inertial frame refers to a framework of reference with no external force. It can be simply be any object that can observe physical phenomena.

It can be derived from the above postulates that time is no absolute, which means time in one inertial frame may not be the same in another inertial frame.

Moreover, as the speed of the inertial frame increases, the time of the inertial frame dilates.

Generally, inertial frames are consistent with respect to the objective physical law, but inconsistent with respect to the subjective observation of physical phenomena.

That is also true for ethics.

With the inertial frames of culture, we are interpreting the objective morality subjectively.

In that way, we may have difference in interpretation of morality, which may results in inconsistency of moral practices.

But actually this is not a problem as we have our own strategy to benefit from it.

We are interpreting the morality with our own contexts, which is different for everybody.

So our interpretation is not the morality themselves, but rather a projection of it, in the form of moral principles.

Our different knowledge gives us different projection of morality as moral principles, which can be combined to reconstruct a more holistic morality.
