The problem of directing a user to stored information, some of which may be unknown to him, is the problem of "information retrieval"... In information retrieval, the addressee or receiver rather than the sender is the active party. Other differences are that communication is temporal from one epoch to a later epoch in time, though possibly at the same point in space; communication is in all cases unidirectional; the sender cannot know the particular message that will be of later use to the receiver and must send all possible messages; the message is digitally representable; a "channel" is the physical document left in storage which contains the message; and there is no channel noise because all messages are presumed to be completely accessible to the receiver. The technical goal is finding in minimum time those messages of interest to the receiver, where the receiver has available a selective device with a finite digital scanning rate.

A number of proposals have been advanced in recent years for the development of ‘general systems theory' which, abstracting from properties peculiar to physical, biological, or social systems, would be applicable to all of them. We might well feel that, while the goal is laudable, systems of such diverse kinds could hardly be expected to have any nontrivial properties in common. Metaphor and analogy can be helpful, or they can be misleading. All depends on whether the similarities the metaphor captures are significant or superficial.
It may not be entirely vain, however, to search for common properties among diverse kinds of complex systems... The ideas of feedback and information provide a frame of reference for viewing a wide range of situations, just as do the ideas of evolution, of relativism, of axiomatic method, and of operationalism... hierarchic systems have some common properties that are independent of their specific content...

Cultural systems will be treated as extensions of the power to learn, store, and transmit information, and the evolution of culture as dependent upon the biological development of these abilities and the cultural developments that actualize them. Man's increasing mastery over the natural world, with its increments of available energy use, can be seen from this point of view as one consequence of his capacity to learn, invent, borrow, store, and transmit the necessary technological and political inventions for the changes of scale involved in increasing utilization of energy. Instead of focusing attention on discontinuities - the invention of tool-making tools, the invention of agriculture, the invention of writing, and the invention of invention as a conscious pursuit-this discussion will focus on the continuities involved and on the extent to which older forms of communication, energy use, and social organization also undergo transformation in the course of cultural evolution.

If then the Courts of justice are to be considered as the bulwarks of a limited Constitution, against Legislative encroachments, this consideration will afford a strong argument for the permanent tenure of Judicial offices, since nothing will contribute so much as this to that independent spirit in the Judges, which must be essential to the faithful performance of so arduous a duty. This independence of the Judges is equally requisite to guard the Constitution and the rights of individuals, from the effects of those ill humors, which the arts of designing men, or the influence of particular conjunctures, sometimes disseminate among the People themselves, and which, though they speedily give place to better information, and more deliberate reflection, have a tendency, in the mean time, to occasion dangerous innovations in the Government, and serious oppressions of the minor party in the community.

What, then, is the animal? First of all, a system of plant-souls. The unity of those plant-souls, which unity nature itself produces, is the soul of the animal. Its world is therefore partly that of the plants - its nourishment, for instance, it receives partly through synthesis from vegetable, and through analysis from animal nature - and partly that of the animals, whereof we shall speak directly. Each product of nature is an organically in-itself completed totality in space, like the plant. Hence, the unknown x which we are looking for must also be such a whole or totality, and in so far it must also have a principle of organization, a sphere and central point of this organization; in short, the same which we have called the soul of the plant, which thus remains common to both. ... The animal is a system of plant-souls, and the plant is a separated, isolated part of an animal. Both reciprocally affect each other.
