Theists: How can predetermined fate and free will coexist?

[Angrboda]

This is a false dichotomy.  That deterministic algorithms cannot also be rational.  What makes you think you cannot evaluate the alternatives in any real sense?  The outcome is determined, but that determination can include rational considerations.  It has been shown by genetic algorithms that task oriented organisms can evolve from basics.  Is rationality not simply another task?

I would agree, that a deterministic algorithm may appear rational, or come to results, that we would consider logical.  However; they also may not.  This argument is more about determining what is rational and what is not, which you cannot do under hard determinism.  The terms determine, evaluate, choose, or consider, don't have any meaning under a hard determinism governed by natural forces.  They are just going to do what they do.

The term evaluate certainly does have meaning under hard determinism. If what they do is perform an algorithm for rational choice then I don't see what the problem is.
