How can we Have a Free Will?

• 'Free will' means that we ourselves do not know the outcome of a free choice until that choice, which is made by our unconscious, has reached consciousness and is thus remembered.
  

• A free choice is random, because neurons are acting on molecular level. The preferences for the different options to be chosen from are determined by our structure as human beings, because structure can force matter into a certain way of action.
  

• In a 'conscious choice', the preferences are predetermined by deliberations and may be close to zero or one. Thus, certain options will be definitely or will definitely not be chosen.

• Overall, a free choice can be understood as a bifurcation, which develops as a Lyapunov instability in the complex structure of our brain.
