Despite the hopes people have had for thousands of years and despite material progress in some places, history has been filled with oppression, crime, violence, war, and poverty.
Hoolimata lootustest, mida inimesed on tuhandeid aastaid hellitanud, ja hoolimata materiaalsest progressist, mis on mõnes paigas toimunud, on ajaloo jooksul esinenud palju rõhumist, kuritegevust, vägivalda, sõdasid ja vaesust.
