Starting from the primary schools, there must be compulsory 'Cosmos' classes throughout the education period. If a man thinks about and understands the universe, he will have wider horizons; he will be much less conceited and much more realistic.
Make walks in the nights to benefit from the education of silence!
Nature is a good teacher; he who can read the nature well, he can learn sagacious things belong to life from it. Once you stepped in the nature, your philosophical education starts. A black vulture teaches you many things; a bear teaches you many things; a bird making its nest and a rosehip which resists being frozen, they teach you many things!
Loneliness is a good education. You learn the things no crowds can teach and you discover the things no crowds can give.
