Context

“We cannot doubt, after this, that qualities are approved of, in proportion to the advantage, which results from them. The decorum or indecorum of a quality, with regard to the age, or character, or station, contributes also to its praise or blame. This decorum depends, in a great measure, upon experience. It is usual to see men lose their levity, as they advance in years. Such a degree of gravity, therefore, and such years, are connected together in our thoughts. When we observe them separated in any person's character, this imposes a kind of violence on our imagination, and is disagreeable.” source
