For all the talk about how psychedelics might transform psychiatric care, there's still a fascinating question at the heart of psychedelic science. Is it the mind-blowing experience that fundamentally changes a person’s outlook on life? Or is it the powerful molecules that rewire the brain?

America is in the midst of a new debate over how we tell our history. You can see it everywhere – in arguments over critical race theory and AP history classes, in museums and state capitals, in the news and on talk radio. It’s fueled in part by an emerging generation of public historians who are re-shaping our national narratives.

There are old folktales and legends of people who can become animals. Animals who can become people. And there’s a lesson for our own time in those shapeshifting stories — a recognition that the membrane between what's human and more-than-human is razor thin.

Human identity cannot be separated from our nonhuman kin. From forest ecology to the human microbiome, emerging research suggests that being human is a complicated journey made possible only by the good graces of our many companions. In partnership with the Center for Humans and Nature and with support from the Kalliopeia Foundation, To The Best Of Our Knowledge is exploring this theme of "kinship" in a special radio series.

Radical politics and radical movements are on the rise everywhere. Against racial violence, and climate change; against gender inequality, corporate greed, low wages, oil pipelines, opioids.  Maybe at heart they all have a common cause.  Maybe they're all — in one way or another — a rebellion against capitalism.

We've always told ghost stories, huddling around campfires, scaring ourselves silly. Today there’s a new venue for spooky stories – YouTube, where creators are turning cobwebby VHS video tapes and other relics of the early internet into a new genre – analog horror. In this hour, we celebrate weird fiction in all its forms, going back to the original eldritch being himself, H.P. Lovecraft.

It’s easy to get caught up in the hype about how psychedelics might revolutionize the treatment of mental illness. But there are also lots of ethical concerns. And probably none are so troubling as the charges of exploitation and cultural appropriation. The fact is, the knowledge about many psychedelics — like magic mushrooms and ayahuasca — comes from the sacred ceremonies of Indigenous cultures. But over the past century, Western scientists and pharmaceutical companies have been going into these cultures, collecting plants and synthesizing their chemical compounds.

Even if science is all about building on the knowledge of earlier discoveries, what is the psychedelic industry's ethical responsibility? Can psychedelics be decolonized?
