No one knows where the borderline between non-intelligent behaviour and intelligent behaviour lies;<br />
in fact, to suggest that a sharp borderline exists is probably silly.<br />
But essential abilities for intelligence are certainly:<br />
&nbsp;<br />
to respond to sitations very flexibly;<br />
to take advantage of fortuitious circumstances;<br />
to make sense out of ambiguous or contradictory messages;<br />
to recognize the relative importance of different elements of a situation;<br />
to find similarities between situations despite differences which may separate them;<br />
to draw distinctions between situations despite similarities which may link them;<br />
to synthesize new concepts by taking old concepts and putting them together in new ways;<br />
to come up with ideas which are novel.<br />
