Determinism

Self determination
This is a theory about how humans would be motivated to grow. When the need is achieved for something, it will grow. This would give humans a fullfilled feeling, they would gain knowledge or gain independence.

Hard determinism
This theory describes how there is no free will in life at all, it all happens for a reason and humans can't change anything and are not responsable for their actions. Humans act in a certain way because they are influenced by things like enviroment, not because they have a free will. Not one event in nature has no cause, nothing occurs without a cause or different causes. This also counts for human actions.

Soft determination
Also named 'Compatibilism'. Here determinism is compatible with free will and responsibility. It even can be seen as determinism is incomprehesible without free will. All actions are caused by internal ( what you want, your free will) and external cause ( upbringing, genetics, ...).
