“Lieutenant Crosshaw says you are a special case!" bellowed Helve. "I do not like special cases! Special cases do not make good soldiers! Special cases do not help other recruits become good soldiers! Therefore, you will not be a special case! You understand me!”

Context: Design is really a special case of problem solving. One wants to bring about a desired state of affairs. Occasionally one wants to remedy some fault but more usually one wants to bring about something new. For that reason design is more open ended than problem solving. It requires more creativity. It is not so much a matter of linking up a clearly defined objective with a clearly defined starting position (as in problem solving) but more a matter of starting out from a general position in the direction of a general objective

Context: Our brains deal exclusively with special-case experiences. Only our minds are able to discover the generalized principles operating without exception in each and every special-experience case which if detected and mastered will give knowledgeable advantage in all instances.

1910s, The Progressives, Past and Present (1910)
Context: Any given case must be treated on its special merits. Each community should be required to deal with all that is of merely local interest; and nothing should be undertaken by the Government of the whole country which can thus wisely be left to local management. But those functions of government which no wisdom on the part of the States will enable them satisfactorily to perform must be performed by the National Government. We are all Americans; our common interests are as broad as the continent; the most vital problems are those that affect us all alike. The regulation of big business, and therefore the control of big property in the public interest, are preeminently instances of such functions which can only be performed efficiently and wisely by the Nation; and, moreover, so far as labor is employed in connection with inter-State business, it should also be treated as a matter for the National Government. The National power over inter-State commerce warrants our dealing with such questions as employers’ liability in inter-State business, and the protection and compensation for injuries of railway employees. The National Government of right has, and must exercise its power for the protection of labor which is connected with the instrumentalities of inter-State commerce.

Epic poetry, Os Lusíadas (1572), Canto X
Context: Great Sir, let never the astonished Gall
The English, German, and Italian,
Have cause to say, the fainting Portugal
Could not advance the great work he began.
Let your advisers be experienced all,
Such as have seen the world, and studied man.
For, though in science much contained be,
In special cases practice more doth see.
