Determinism

[Caecilian]

In a sense, determinism is like destiny's long lost twin brother.

I quote Wikipedia: "Determinism is the philosophical view that every event, including human cognition, behaviour, decision, and action, is causally determined by the environment."

The Wiki quote is actually a bit misleading. When they talk about cognition, most people take 'the environment' to mean 'the external environment'- i.e. the environment outside of the organismic boundary. In the above quote, 'the environment' means, in effect, 'everything that there is'. To reiterate: in determinism, everything is causally determined by something.
