This isn't about his philosophy and beliefs. There are some good reasons to believe he is the Harvard professor referenced in the statement from one of the alleged victims: "A quirky little man with wild, mad professor white hair."
The article exonerates him because Pinker himself claims to have hardly known the guy? By the way, that could be true, and he still could've paid Epstein Island a visit, once. It seemed a haven for awkward, strange men who ordinarily wouldn't get within paw's reach of hot women. Sounds like a description of a whole lot of dudes in your pursuit.
I'm sure many of the academics who chummed around with Epstein did it because they wanted him to give them or their departments money. I'm also sure that some were less interested in that and more interested in the young women who perpetually surrounded him. Epstein brought them along when he strolled into those campuses.
