What is Determinism, in the context of freewill?

Determinism is the belief that humans have no freewill to choose to do as they wish, due to the influence of external forces upon us. Such external forces may, for example, be how we have been conditioned by our parents. Determinism is an umbrella term under which fall different types, for example biological determinism or theological determinism. One scholar who looked to develop determinism was John Hospers. He postulated that a universal set of factors may be responsible for conditioning us to undertake certain events. For example, whenever we eat blueberry pie, we will commit murder. This is of course an absurd example, but it demonstrates that unknown combinations of different actions may lead us to act in certain ways, and so humans would not be free to choose their actions.
