Education is humanity’s central problem. If we could provide a correct form of education and grounding to at least one generation, we could then be certain that all future generations would be brought up suitably and live optimally. This is because each generation that receives the correct method of education can and will be capable of adequately raising the next generation.
Alternatively, the failure to raise such a generation in even one society, and observing each succeeding generation as inferior compared to the previous, bears witness to the fact that humanity has never possessed the correct method of education.
