In a well-balanced, reasoning mind there is no such thing as an intuition - an inspired guess! You can guess, of course - and a guess is either right or wrong. If it is right you can call it an intuition. If it is wrong you usually do not speak of it again. But what is often called an intuition is really impression based on logical deduction or experience. When an expert feels that there is something wrong about a picture or a piece of furniture or the signature on a cheque he is really basing that feeling on a host of a small signs and details. He has no need to go into them minutely - his experience obviates that - the net result is the definite impression that something is wrong. But it is not a guess, it is an impression based on experience.
