I have heard that humans have a limited or constrained free will, especially when biological limitations are brought up. However, Merriam-Webster dictionary says:

Limited

1a: confined within limits: RESTRICTED

And:

Constrain

1a: to force by imposed stricture, restriction, or limitation

Also, among the many definitions of free is:

Free

8a: not obstructed, restricted, or impeded

Does this mean limited free will is the same as restricted unrestricted will?

What is limited free will?
