“In order to speak of something as a system, we must be able to state clearly:

(1) the holistic behavior which we are focusing on;

(2) the parts within the thing, and the interactions among these parts, which cause the holistic behavior we have defined;

(3) the way in which this interaction, among these parts, causes the holistic behavior defined.”

...

"We must not use the word system, then, to refer to an object. A system is an abstraction. It is not a special kind of thing, but a special way of looking at a thing. It is a way of focusing attention on some particular holistic behavior in a thing, which can only be understood as a product of interaction among the parts. "

...

"Furthermore, even though we call a thing a system when we try to view it as a whole, this does not mean that we ever really view the thing in its entirety."

...

“The systems point of view is not neutral. It will change your whole view of the world. It will lead you to realize that the most important characteristics of human individuals are products of their interactions with other people.”

...

“The system viewpoint is a modern, disciplined, version of the sense of wonder. It is that view of things which man takes when he becomes aware of oneness and wholeness in the world.”

...

“To make objects with complex holistic properties, it is necessary to invent generating systems which will generate objects with the required holistic properties. The designer becomes a designer of generating systems — each capable of generating many objects — rather than a designer of individual objects.”

To make a collection is to find, acquire, organize and store items, whether in a room, a house, a library, a museum or a warehouse. It is also, inevitably, a way of thinking about the world – the connections and principles that produce a collection contain assumptions, juxtapositions, findings, experimental possibilities and associations. Collection-making, you could say, is a method of producing knowledge.
During the Renaissance, private citizens collected items of note in their own homes, often in a specially designated room known as a Wunderkammer, or cabinet of wonders. Aristocrats, monks, scholars, academicians, natural scientists and wealthy private citizens: the slightly motley group who made up the early modern public sphere were the initial protagonists. The compulsive interest of such people in collecting expressed itself as a drive to collate and understand significant objects: the fossils, minerals, specimens, tools and artisanal products that provided evidence for our knowledge of and theories about the world. And without modern national institutions – there was no British Library or Natural History Museum in London, or Library of Congress in Washington – it fell to interested parties to take up this job themselves.
Though the aim of amassing evidence may sound like a rather scientific way to think about collecting, it is necessary to remember that the hard distinction between science and art which marks more recent centuries was not evident as late as the sixteenth century. The separation of art and the humanities on the one hand, and science on the other, is a fundamental feature of modern life, but it also constitutes a loss.
