Friedrich Schiller said this quote

It seems a bad thing and detrimental to the creative work of the mind if Reason makes to close an examination of the ideas as they come pouring in -at the very gateway, as it were. Looked at in isolation, a thought may seem very trivial or very fantastic; but it may be made important by another thought that comes after it, and in conjunction with other thoughts that may seem equally absurd, it may serve to form a most effective link. Reason cannot form any opinion on all this unless it retains the thought long enough to look at it in connection with the others. On the other hand, where there is a creative mind, Reason -so it seems to me- relaxes its watch upon the gates, and the ideas rush in pell-mell, and only then does it look them through and examine them in a mass.
