Summary of the three pillars of a Reasonable Person

The three pillars of Immanuel Kant can be summarized this way.  

Logic is the first pillar of Immanuel’s reasonable human theory. This logic has a common sense factor, i.e. a dog cannot be a cat because 1=/=0. 1 can only equal 1 and no other number because these terms have been defined but reasonable people, ideally. This style of logic may seem trivial at first glance but can become more abstract with more difficult situations, i.e. is it logical to kill one person for the safety of many other humans, yes but morally is a different story, we will get to that later.

Physics is the second pillar towards a reasonable state of mind. This physics is not conventional physics as we know it today but rather the laws of the natural world that deal with abstract concepts including but not limited to: time, space, one’s self, knowing, or knowledge. This is an empirical form of rationality, experienced not taught.

Ethics is the third and last pillar of the structure of reasonability. Ethics deals with morals and what a reasonable person would think is right, throwing all emotion and bias opinions out the window.  Morality and duty are intertwined in Kant’s theory/ argument. There is one duty type that can describe if a duty is morally right but can be written three different ways: The Motive of Duty, the Formal Principle of Duty, and To Act Morally whenever it may be to act morally. Back to the example in the first pillar, logic states that one death is better than more than one death but morally do each of these lives not independently matter? The man that dies for the others, was he good or evil? Would it be the duty of the single person to save the others.
