People who think of life as being like climbing a mountain are treating their own existences as lines. As if there is a line that started the instant one came into this world, and that continues in all manner of curves of varying sizes until it arrives at the summit, and then at long last reaches its terminus, which is death. This conception, which treats life as a kind of story, is an idea that links with Freudian etiology (the attributing of causes), and is a way of thinking that makes the greater part of life into something that is “en route.”
