Generally they mean only that they will do as they choose, in the confidence that no one will know their vagaries; and at the utmost only that they are willing to act contrary to the opinion of the majority because they are supported by the approval of their neighbours. It is not difficult to be unconventional in the eyes of the world when your unconventionality is but the convention of your set.

Moreover, this formation will be continuous because the reactions which started it are renewed incessantly.
