„And what is death? It is the change in the living process of a particular body. Integration ends and disintegration sets in. (…) In death only the body dies. Life does not, consciousness does not, reality does not. And the life is never so alive as after death.“

„They [laboratory groups] bypass such questions as how one comes to know that a problem exists, what it does to solution adequacy to be working on several different things concurrently with problem solving, what it's like to go about solving a felt, intuited problem rather than an explicitly stated consensually validated problem which was made visible to all members at a specific point in time.“

„Design is really a special case of problem solving.“

Kontextus: 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

„This realistic image, however, does not catch at all what really is, but what should not be - death and misery - what should not exist, from our moral and humanistic point of view. And at the same time making an aesthetic and commercial, perfectly immoral use and abuse of this misery. Images that actually testify, behind their pretended "objectivity", of a deep denial of the real, and of an equal denial of the image - assigned to present what does not even want to be represented, assigned to the rape of the real by burglary.“
