Common sense invents and constructs no less than its own field than science does in its domain. It is, however, in the nature of common sense not to be aware of this situation.
If the present civilisation does not acquire some stable moral fondations ("bases morales stables", Fr.), its existence will hardly be more assured than that of the civilisations that have preceeded it, and which have fallen (or collapse, or failed).
Society, to be sure, does not like this very well; it saith, Whoso goes to walk alone, accuses the whole world; he declares all to be unfit to be his companions; it is very uncivil, nay, insulting; Society will retaliate.
I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.
An Englishman is a person who does things because they have been done before. An American is a person who does things because they haven't been done before.
