What Exactly Gives Something Free Will?

(If you are in IME 4020, this is a topic for Dr. Young's side of the class.)

Imagine that your local mad scientist has created an extremely sophisticated robot, "Milo". Milo has consciousness, intelligence, and indeed all the characteristics of a human mind except (possibly) one. The robot Milo (may or may not) lack free will. The mad scientist wants Milo the robot to have free will, and asks for your help in (possibly) altering the robot so that it has free will.

<added 3/23/25> As he tells you all about Milo, the scientist is working on Milo's left knee joint, while Milo lies on the workbench, idly twiddling his thumbs. Milo takes a second to wave and say "hi" while the scientist closes Milo's left poleyn, and checks the flexibility of the knee joint. After this, Milo hops down from the bench, checks the joint for himself, and asks if its okay with everyone if he leaves for a few hours, as he has an appointment to play chess with the village blacksmith.

Your assignment is to figure out what mechanism, or way of being, is necessary in order for something to have free will.

Remember, it may turn out to be the case that Milo the robot already has free will, and the scientist, for some reason, hasn't noticed or realized that they have already created a free-willed robot.(<added 3/23/25> Remember that, as stated above, Milo has consciousness, intelligence, and indeed all the characteristics of a human mind.)

For reference, remember that the existence of free will means that an entity has a "will", which is an internal faculty of being able to decide for itself what it is going to do, based on it's own ideas and goals, and that it also occasionally has the freedom to act on its own decisions, rather than being coerced by some external force to do things it would not, on its own, decide to do. (<added 3/23/25> Keep in mind that, as stated above, Milo has consciousness, intelligence, and indeed all the characteristics of a human mind.)

1. A will is a mechanism inside a specific being that allows that being to form preferences, desires, and intentions, decide between different courses of action, and initiate their own actions action on those decisions. (<added 3/23/25> At this point, it might be a good idea to recall that Milo has consciousness, intelligence, and indeed all the characteristics of a human mind.)

2. Coercion is when, by force or threat, one being completely imposes their will on another being, making them do something they would otherwise never do. Unlike influence, constraint or restriction, coercion removes a beings freedom of action, placing them in a situation where they have no other choice. 

3. Freedom is a condition in which a being, while perhaps subject to various influences, constraints, and restrictions is still able to pick out and perform the action that they most think they should do, out of a range of several possible actions. Freedom is thus basically the absence of coercion.

4. Free Will is when the will is at least sometimes free. If robot Milo ever gets to act on their own decisions, without being forced by others to do things they don't want to do, then Milo has free will. If it is the case that Milo has no will, or that Milo's every action is always coerced, then Milo has no free will.

Do NOT assume that the robot is necessarily constructed in a way that will not allow it to have free will.

If you accept that it is technically possible to create a robot with free will, then you will have to say just what kind of mechanism would have to be installed in the robot's brain, or what it already has in its brain, in order to give it exactly the same kind of free will that human beings have, or appear to have.

If you do not accept that it is technically possible to create a robot with free will, then you will have to say just what kind of mechanism you think human beings have that gives them free will. <edit 3/23/25: If you think there's some mechanism robots cannot have,> , you will have to do more than just say "machines can't do this." You will have to say what this mechanism is, and why something that a human brain does using neurons and synapses cannot be done with some mechanism that does the same things as neurons and synapses.)

<added 3/23/25> Again, if you think there's something humans have that robots don't, you will have to say what this mechanism is, and why something that a human brain does using neurons and synapses cannot be done with some mechanism that does the same things as neurons and synapses.

If you cannot think of a mechanism that a human being could have, (even if it couldn't be installed in a robot), that would give it free will, then you should not assume that a robot cannot have whatever it is that gives humans free will. (changed 4/9/23.)
