In the external, or physical, world, we're all aware of standard cause and effect.

転換語

You know, "Object A acts upon Object B with Force X." We all get that, because it applies to

程度の副詞

just about everything -- from electrons to athletes.

But now consider events in your internal, or mental, world. What causes your thoughts?

Some of our thoughts have external causes, like when we touch something and suddenly

realize it's hot. We don't deliberate whether or not to pull our hand away. Our brain has

already fired the instruction to do so -- involuntarily. In some strange sense, "we" didn't really

pull our hand away at all -- because "we" didn't choose to do it.

A second cause of our thoughts is internal. Say you're thinking about giving a big presentation

and as you do so, you get increasingly nervous, and your blood pressure and your heart rate jump up.

Now, nothing external is acting upon you. You're doing all the "causing" internally, right?

Your anxious thoughts are causing your brain to send signals to your heart, and we get that.

But now, I want you to consider a third category of your thoughts -- it's your conscious choices

-- something as simple as choosing where to go for lunch.

Now when you introspect, when you think about your thinking, do you believe that you are

the active agent in charge of the process, or that you are just a passive recipient of

the instruction -- that you have no choice in the matter, it's all external forces --

be they environmental, genetic, chemical, biological, or neurological?

In other words, do you think all your thoughts have external causes beyond your control,

or do you think that you control some, if not most, of your thoughts?

Now let's stay with our lunch example for a second... back to the question...I ask you

"Where do you want to go for lunch today?"

Now, if all you are is a brain, an exhaustively physical system of neurons and synapses,

then there's no "you" that's gonna be making a "choice" at all. Your thought processes

are basically just a complex series of colliding electron-dominos crashing into one another.

It's just physical cause and effect, right -- something that can be exhaustively understood

in terms of physics and chemistry? There's no "you" that's an agent that's deliberating,

And that's why, if you are just a brain, you cannot have free will.

You would just be a physical machine -- a very complex but programmed computer.

But, if you're something more than your brain -- if you're the thing that has the brain --

then, when I ask you "Where do you want to go for lunch?," you're going to start deliberating

-- you're going to be weighing your taste preferences, the commute time, perhaps even

counting calories. You'd be weighing various reasons to choose one place over another.

You wouldn't be caused to think about any of these things. You would choose to think

about these things, and you could stop anytime you wanted to.

So, what we have here, therefore, are two different types of things: an immaterial mind

and the material brain. You are the thing that has the brain -- you are not your brain.

Now look, even if you were the world's foremost brain expert, and you knew what was happening

with every electron in someone's brain at a specific, particular moment, you still wouldn't

have a clue about what's going on inside that person's mind. Surgeons can have access to

my brain, but only I have access to my mind. This is what makes you human and not a machine.

Psychology, the study of the mind, is not reducible to physics, and biology, and chemistry.

Yet, there are many materialists -- people who believe that physical matter is all that exists,

that the only reality -- including every thought, every feeling, every mind,

every will, all of this is totally explained in terms of matter in motion, simply physical phenomena.

These materialists believe that we're no more than robots and that free will

Now, why do they believe this? Because they understand that the moment they acknowledge

that free will exists, that there really is an immaterial you beyond the physical realm,

that there really is a mind, not just a brain, then there has to be something non-physical

that accounts for our non-physical minds.

Now when you exercise your freewill and you choose to think about all of this

-- you're gonna probably reason -- just like I did -- that there is a Great Mind

that accounts  for the origin of your mind.

But again, that's your choice -- it's evidence of your free will.
