Colonization in Africa was much more than a land grab. It was a project to replace — and even erase — local cultures. To label them inferior. Music, arts, literature and of course language.

Today we're bringing you a conversation from "Kelly Corrigan Wonders." As a podcaster, Kelly is a kindred spirit – curious, genuine, caring — and this conversation is from a series about one of TTBOOK’s own core values – intellectual humility.  It’s about the magic that happens when we stop trying to be right all the time. In this episode, Kelly talks with researcher and academic Daryl Van Tongeren about how we come to conclusions and what, if anything, can interrupt the creation of overconfident, under-researched, ironclad, and divisive by nature convictions. Daryl teaches at Hope College in Michigan and researches the social motivation for meaning and its relation to virtues and morals.

In the world of internet influencers and YouTube stars, it’s not enough to be ordinary anymore. You need to be special. But where did this craze for personal branding come from? Why are we so obsessed with ourselves? To understand this cult of the self, we need to go back to 19th century spiritual movements and the rise of the huckster — and also the myth of rugged individualism.

2019 was an important year throughout the African diaspora — the 400th year since enslaved Africans first arrived in the United States. In Ghana — once the center of the European slave trade — 2019 was declared "the year of return" and the start of a campaign to encourage descendants of enslaved Africans to re-connect with the land of their ancestors. Thousands of African-Americans made the trip to Ghana — and many have decided to stay. They're fed up with police brutality and systemic racism in the US, ready to build new lives in Africa — and their number is growing.
