The difference between natural objects and an artifact is that natural objects have self movement. Aristotle defined the difference between a natural object and an artifact when he stated, “In contrast to these, a bed, a cloak, or any other artifact-insofar as it is described as such i.e. as a bed, a cloak, or whatever, and to the extent that it is a product of a craft-has no innate impulse to change; but insofar as it is coincidentally made of stone or earth or a mixture of these, it has an innate impulse to change and just to that extent. This is because a nature is a type of principle and cause of motion and stability within those things to which it primarily belongs in their own right and not coincidentally.” The natural objects are changed to artifacts through crafts but they have an innate impulse of self movement to convert through time to their natural state, and they will all turn into that state when all animals with reason are extinct from earth.
Aristotelian theory of gravity
Although Aristotle wrote several works on Ethics, the major one was the Nicomachean Ethics, which is considered one of Aristotle's great works and discusses virtues. The ten books which comprise it are based on notes from his lectures at the Lyceum and were either edited by or dedicated to Aristotle's son, Nicomachus.
In Nicomachean Ethics, Aristotle focuses on the importance of continually behaving virtuously and developing virtue rather than committing specific good actions. This can be opposed to Kantian ethics, in which the primary focus is on individual action. Nicomachean Ethics emphasizes the importance of context to ethical behavior – what might be right in one situation might be wrong in another. Aristotle believed that happiness is the end of life and that as long as a person is striving for goodness, good deeds will result from that struggle, making the person virtuous and therefore happy.
