Wanted: Irreducible definition of design ...  

A matter which has
much to do with execution, but perhaps also with design, is that perfection -- or some kind of beauty, at least -- seems to me to be the absence of error or fault (ugly wood grain, or an unfaired curve, or simple damage, for instance).

. . .because
such faults distract the eye and the mind from the appreciation of the form (and function ?) of the object. . .

'We as human beings are a product of what we hear & speak, smell & see, of what we touch & do not. We are a product of what we accept and reject, our designs created are of simular existence, going through the same mature or naive progression...There to the accepting or/& rejecting individual will you find ideal design'
