This paper presents a general conceptual framework for systems built up of elements causally coupled to each other, when such causal influence can be considered as to take place through welldefined channels connecting the elements. In Part I, general deterministic systems are treated and in Part II appearing in the forthcoming issue the treatment is confined to systems with elements exhibiting linear behaviour. Special attention is given to the relationship between element behaviour, system structure and system behaviour.

In this paper new forms of computer simulation of nonlinear phenomena in Newtonian mechanics are developed. Energy conservation of the discrete formulations is established and applications are made to the studies of nonlinear oscillation, planetary orbits, nondegenerate threebody problems, and nonlinear string vibrations.

The thesis that conscious states are processes in the brain that can be described in terms of the physical sciences is criticized as being scientifically implausible in several respects. A modified version of this thesis is proposed according to which conscious states are processes of the organism's central informationprocessing system, by which it is enabled to maintain flexible control over its behavior in a changing perceptual environment. Description of these processes requires the categories of cybernetics, specifically those of information and of negative feedback.

It has been argued that Gdel's theorem proves the case against the possibility of artificially intelligent machines, capable of achieving the same level of intelligence as human beings. The argument is that if a human being were a logistic system L, how is possible that it can see certain theorems to be provable when Gdel shows that such a system cannot demonstrate whether such theorems are provable or not. The fallacy is that the theorems of L that the human can see to be provable are a subset L of L, and that for some theorems of L and not L the human is subject to the same limitation as the machine.

In this paper an attempt is made to find a mathematical model for a number of mainly electrophysiological results concerning pattern recognition of mammals. After a short introduction to the applied theory of linear nervous nets, the investigations in the retina and geniculate body are interpreted as filters for space and timedependent oscillations. By application of the detection theory a functional model of the cortex regions 17, 18 and 19 is formed. The classification process is considered to be the spatial crosscorrelation, but by means of the present results it is not possible to draw complete conclusions on the structure of the recognition process.
