I have been on this planet for 58 orbits and now I realize that, looking back on things, it has always been this way and there were no good old days - only days of total obliviousness and blind nostalgia. The reason why some don’t want real history taught in schools is that they prefer their kids share the obliviousness and not challenge them to lift the scales from their eyes.
The truth is we have always lived on a knife blade, but we only can do so by holding the conflicting ideas in our mind that we are both on a knife blade and living. Existing requires both optimism and realism.
