All human behaviour is instinctive.
We are members of the animal kingdom (specifically mammals) and our behaviour is governed by the same laws as every other animal on this planet.
How we achieve these two fundamental laws is dependent on:
The animal world is kept in balance by:
- Disaster (gradual or sudden)
- Diversity of species
All animals attempt to use and/or restrict C to achieve A. For billions of years natural selection was the means by which all species that we see in our world today survived.
Because of natural selection humans (Homo sapiens) have evolved genetically to be more dextrous and intelligent and able to live in a greater diversity of environments than other animals.
Although human beings on the face of it have free will in reality that free will is restricted by our acting on instinct, so our free will is constrained by our obeying the basic laws A and B2.
Because of how we have evolved we are better at manipulating C but for all our apparent intelligence we have failed to recognise that manipulating C is counter productive because by natural law C must always be in balance. If we are good at controlling diseases then resources are put under stress if we then increase resources the environment and diversity is put under stress and so it goes on. Human intelligence it appears has not evolved sufficiently enough to tackle the conundrum of being of the animal world and all the laws it must obey and how to break free from those laws without succumbing to those laws.
