Fernald has no entry of its own for daring; he lists it under brave.
Where he writes about it:
The daring step out to defy danger; the dauntless will not flinch before anything that may come to them; the doughty will give and take limitless hard knocks. — from brave
Courageous is more than brave, adding a moral element: the courageous man steadily encounters perils to which he may be keenly sensitive, at the call of duty; the gallant are brave in a dashing, showy, and splendid way; the valiant not only dare great dangers, but achieve great results; the heroic are nobly daring and dauntless, truly chivalrous, sublimely courageous. — from brave
