If you’re looking for a conversation that goes deep fast and leaves you thinking, “Huh, I need to think about this,” go find the man in the crown sitting outside the legislature, David Arthur Johnston. He has been there most days for the last 18 months. Author of “The Right to Sleep” and a long-time challenger of conventional thinking around free will, the 53-year-old has lived the last 25 years without money, even burning the serial numbers off the bills that passersby occasionally give him when they mistake him for a panhandler. He notes he’s happy to take whatever people give him, but no money, and no income assistance. “I’ve always been a minimalist and a pragmatist. When I was 12, I quit putting sugar in my coffee, because I figured I was going to be poor all my life so might as well get used to it,” says David, who was a plaintiff in the last big court case that in 2009 threw out the City’s bylaws prohibiting camping in parks. People need to let go of the notion that free will is real, he says: “Once you let that go, then however stupid or crazy a person is, you can’t hate them. This idea that a person chooses, and therefore can choose badly – you can move past that.”
