"What passes for optimism is most often the effect of an intellectual error"

This quote by Raymond Aron recommends that what is typically perceived as optimism is actually an outcome of an intellectual mistake. He indicates that people frequently error optimism for something else, and that this is because of an error in their thinking. This might be due to the fact that they are ruling out all the facts or because they are not taking a look at the circumstance objectively. It could likewise be since they are not considering the possible risks or effects of their choices. In other words, they are not thinking critically and are instead depending on a false sense of optimism. This quote functions as a reminder to believe seriously and objectively prior to making choices, as optimism can be a hazardous thing if it is not based upon facts and reality.
