"In science , all conclusions are provisional, subject to new evidence and better arguments, the very antithesis of religious faith."

Like 'real', 'free' is only used to rule out the suggestion of some or all of its recognized antitheses. As 'truth' is not a name of a characteristic of assertions, so 'freedom' is not a name for a characteristic of actions, but the name of a dimension in which actions are assessed.
