Simply answered. It is the thought process that concludes, since everyone is born with these same three instincts in them, they can be governed by one universal set of laws. administered by one democratic government that includes a bill of rights for all people. It will explain to the masses that following one leader of a sect to an extreme is an illogical reaction. (A true leader would never recommend you kill yourself.) This leads me to the logical conclusion that leaders can excite groups of people to be so pleased with being part of the group that they will commit heinous actions to be part of the group. This instinct that can override the other two is called The Herding Instinct.
The acceptance of the three natural instincts theory by the masses could lead to the Age of Inclusion where there are no more wars between nations. Unfortunately there will always be those with an out of control instinct forcing the need for us (humans) to always have militaries and police forces.
Examples of people who are out of control of their pleasure instinct; A rapist or a person on drugs that is not functioning in our society.
Examples of people who are out of control with their will to survive instinct; a con man, a thief and in some cases a murderer.
Examples of people who are out of control of their herding instinct; a terrorist bomber, a sports fan that attacks another fan.
