Part 1 When the objects of an inquiry, in any department, have principles, conditions, or elements, it is through acquaintance with these that knowledge, that is to say scientific knowledge, is attained.

Natures Nature, according to Aristotle, is an inner principle of change and being at rest Physics 2. This means that when an entity Aristotles physics essay or is at rest according to its nature reference to its nature may serve as an explanation of the event. We have to describe how—to what extent, through what other processes, and due to what agency—the preconditions for the process of change or of being at rest are present, but once we have provided an account of these preconditions, we have given a complete account of the process.

The nature of the entity is in Aristotles physics essay of itself sufficient to induce and to explain the process once the relevant circumstances do not preempt it. Natures as inner principles of change and rest are contrasted with active powers or potentialities dunameiswhich are external principles of change and being at rest Metaphysics 9.

When a change, or a state of rest, is not natural, both the active and the passive potentiality need to be specified. Natures, then, in a way do double duty: Because natures—beside the active and passive potentialities—are ultimate grounds in causal explanations, Aristotle sets out how they are integrated with the doctrine of causation.

The four causes An explanation for a state of affairs must specify some feature or some object in general, some abstract or concrete entity which is responsible for it. The entity responsible is, Aristotle submits, a cause aitia or aition, words used interchangeably by Aristotle.

The varieties of responsibilities are grouped by Aristotle under four headings, the so-called four causes. Understandably, both of them can be responsible for the features and the behaviour of the entity they make up. Hylomorphic analysis, together with the separation of the material and formal causes as distinct types, implies that if something is explicable in terms of matter or form, explanations in terms of form will be different in kind from those given in terms of matter.

As a rule there is a collaboration between these causes: Accordingly, these causally relevant entities give rise to a hierarchic structure of explanation.

This suitable matter brings with it the features required by a given hylomorphic composite. These features, then, are on the one hand the contribution of the matter, and as such the matter is the material cause of these features of the composite entity, whereas on the other hand they are indispensable presuppositions for the realisation of the form, and to that extent their presence is prompted by the form.

Aristotle sometimes illustrates his point by appealing to the matter required for the construction of a house. If there is a house to be built, one needs building bricks, slabs, mortar, etc.

Each part provides material with properties within a definite range of the sort required for a house to come into being. A house cannot, for example, be made out of liquid water. This sort of matter provides potentialities not suited to the form of house.

Explanations often specify entities beyond the role played by the matter and the form of the entity itself. These cases are grouped by Aristotle as efficient or moving causes on the one hand and as final causes on the other.

Efficient causes operate in a straightforward manner by initiating processes and bringing about their effects, whereas final causes account for processes and entities by being what these processes and entities are for, what they objectively intend to attain.

On the contrary, an efficient cause can also be internal. In cases in which the efficient cause is internal, it will be, in its specific function, one of the parts, or even the formal aspect, of the entity caused to move.Aristotle: Politics.

In his Nicomachean Ethics, Aristotle ( B.C.E.) describes the happy life intended for man by nature as one lived in accordance with virtue, and, in his Politics, he describes the role that politics and the political community must play in bringing about the virtuous life in the citizenry.

The Politics also provides analysis of the kinds of political community that. On the Security of Walls. Interesting history of the security of walls.
