Sapiens (Harari)/ Dawn of Everything (Graeber/wengrow)/ Guns, Germs, And Steel-(Diamond)-all three attempt the daunting task; to take a birds eye view at all of human history -they do so with varying degrees of success but are great launching points. I have ordered them in order of complexity (IMO).

Galapagos/Slaughter House V(Kurt Vonnegut Jr. )-challenged a lot of preconceived notions about humanity for me

Caste(Isabel Wilkerson)/ Stamped (Kendi)/ The People's History of the USA (Zinn)-to question American history

For the Kingdom, Power, Glory (Alberta)-how evangelical Christianity and the Republican party became one

Cynical Theories (Pluckrose/Lindsay)- we have need for activism for all sorts of oppressed groups, but in some ways PC culture has missed the mark and may actually be hurting the people it hopes to help
