Absent the names of the persons involved, the questions are meaningless.

We get our hackles up at nameless posters on this forum and the problems they present.

How could it be otherwise?

Well, if the problem presents itself such that one set of neurons, in one part of the brain is preferentially fired over another set, different solutions will result.

Philosophers compare this problem to a second scenario, sometimes called the footbridge problem, in which a train is again heading toward five people, but there is no spur. Two bystanders are on a bridge above the tracks and the only way to save the five people is for one bystander to push the other in front of the train, killing the fallen bystander.

I can't figure out how dumping yet another person in front of a train would save any of them. Wouldn't that just kill 6 people instead of five? What about the folks on the train?

But let's assume the one you, the other bystander, would push could cause the train to derail and somehow save the others... it isn't right to toss someone else in to do the job when you can do it yourself. So their belief that the situations they propose are essentially the same is a bit of a stretch.

The reason for this lies not in the sequence but in the structure.

I'm not sure we can be that precise. I know that we can see the firing of a single neuron in a fly's brain when visually stimulated but I don't think that human thought is circumscribed to that level.

I have no idea where you are going with that. Most people view the genetic code as a linear sequence of information, independent of structure, much like the code of a computer program.

We have a hint here, in this study.

That's why they use these kinds of problems. The numbers work out the same, but one situation feels wrong while the other doesn't.

But you and I know that it is not. That is what my post demonstrates. Even a computer program is not just simply a linear sequence of instructions. A program can be rearranged linearly to a certain degree and function precisely the same(excluding minor timing variances) yet you can invert one logical test and produce profound changes in operation. I again point out the "language" aspects of the code.

Here are some hot events.

Rank and organization: Sergeant First Class, U.S. Army, Battery A, 2d Battalion, 320th Field Artillery, 101st Airborne Infantry Division (Airmobile). Place and date: Tam Ky, Republic of Vietnam, 15 October 1967. Entered service at: Winnsboro, S.C. Born: 15 July 1933, Winnsboro, S.C. Citation: Sfc. Anderson (then S/Sgt.), distinguished himself by conspicuous gallantry and intrepidity in action while serving as chief of section in Battery A, against a hostile force. During the early morning hours Battery A's defensive position was attacked by a determined North Vietnamese Army infantry unit supported by heavy mortar, recoilless rifle, rocket propelled grenade and automatic weapon fire. The initial enemy onslaught breached the battery defensive perimeter. Sfc. Anderson, with complete disregard for his personal safety, mounted the exposed parapet of his howitzer position and became the mainstay of the defense of the battery position. Sfc. Anderson directed devastating direct howitzer fire on the assaulting enemy while providing rifle and grenade defensive fire against enemy soldiers attempting to overrun his gun section position. While protecting his crew and directing their fire against the enemy from his exposed position, 2 enemy grenades exploded at his feet knocking him down and severely wounding him in the legs. Despite the excruciating pain and though not able to stand, Sfc. Anderson valorously propped himself on the parapet and continued to direct howitzer fire upon the closing enemy and to encourage his men to fight on. Seeing an enemy grenade land within the gun pit near a wounded member of his gun crew, Sfc. Anderson heedless of his own safety, seized the grenade and attempted to throw it over the parapet to save his men. As the grenade was thrown from the position it exploded and Sfc. Anderson was again grievously wounded. Although only partially conscious and severely wounded, Sfc. Anderson refused medical evacuation and continued to encourage his men in the defense of the position. Sfc. Anderson by his inspirational leadership, professionalism, devotion to duty and complete disregard for his welfare was able to maintain the defense of his section position and to defeat a determined attack. Sfc. Anderson's gallantry and extraordinary heroism at the risk of his life above and beyond the call of duty are in the highest traditions of the military service and reflect great credit upon himself, his unit, and the U.S. Army.

Yes, obviously, but what I find interesting is the passive voice. What 'prefers' the firing of one set of neurons over another - another set of neurons? How do mere physiological processes account for the notion of morality itself, with its attendant concepts of freedom, agency, obligation, accountability, and dignity? How is it that mere electrochemical reactions in the brain lead logically to any coherent, intelligible concept of 'right' or 'wrong'?

Cordially,

Nature has an article on the subject.

At the same time, there could be good reasons to trust our gut responses, he suggests. "Emotions may well be important adaptations. We don't have to write them off as silly, murky, irrational responses."

I don't think there is anything "mere" about the workings of our brains.

I don't know what heroism has to do with the decision making process.

Because of blindness of the experimenters in the following problem, one that they posed.

Two bystanders are on a bridge above the tracks and the only way to save the five people is for one bystander to push the other in front of the train, killing the fallen bystander.

If one can push another into the path of a train one can sacrifice themselves.

*AUSTIN, OSCAR P.

Rank and organization: Private First Class, U.S. Marine Corps, Company E, 2d Battalion, 7th Marines, 1st Marine Division, (Rein), FMF. Place and date: West of Da Nang, Republic of Vietnam, 23 February 1969. Entered service at: Phoenix, Ariz. Born: 15 January 1948, Nacogdoches, Tex. Citation: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as an assistant machine gunner with Company E, in connection with operations against enemy forces. During the early morning hours Pfc. Austin's observation post was subjected to a fierce ground attack by a large North Vietnamese Army force supported by a heavy volume of hand grenades, satchel charges, and small arms fire. Observing that 1 of his wounded companions had fallen unconscious in a position dangerously exposed to the hostile fire, Pfc. Austin unhesitatingly left the relative security of his fighting hole and, with complete disregard for his safety, raced across the fire-swept terrain to assist the marine to a covered location. As he neared the casualty, he observed an enemy grenade land nearby and, reacting instantly, leaped between the injured marine and the lethal object, absorbing the effects of its detonation. As he ignored his painful injuries and turned to examine the wounded man, he saw a North Vietnamese Army soldier aiming a weapon at his unconscious companion. With full knowledge of the probable consequences and thinking only to protect the marine, Pfc. Austin resolutely threw himself between the casualty and the hostile soldier, and, in doing, was mortally wounded. Pfc. Austin's indomitable courage, inspiring initiative and selfless devotion to duty upheld the highest traditions of the Marine Corps and the U.S. Naval Service. He gallantly gave his life for his country.

That's a bit silly, AndrewC. The problems are given with options. Heroic alternatives, and one can think of many, are not given as a choice. The elegance in an experiment is to get an answer with the simplest design possible. Throwing heroics into the mix, something that not everyone resorts to, is adding a complicating factor. It would be interesting for a future study, but it is certainly not a design flaw for this study.

Speak for yourself! (just kidding).

Put another way though, are moral "right" and "wrong" solely electrochemical reactions in the brain?

Of course these concepts are natural functions of our brains.

If morality is a property of matter, then how do physical and chemical interactions, which by their very nature are coercive force, lead to a moral prescription or a moral prohibition?

How does an idea, a statement, such as (lets pick one out of thin air) "Concepts are natural functions of our brains" arise from molecules? I guess what I trying to ask is, what is the origin, the meaning, and the significance of the concept "morality", if the concept itself is nothing but the result of brute forces of chemistry or electricity?

What if the pulses of depolarization in my brain traverse different pathways? What if the molecules that produce the idea, "morality" happen to go a different direction? Does morality then change? What if the neurotransmitters produce the output, "Concepts are NOT natural functions of our brains"?

Under a purely naturalistic premise I think that my brain could only be physically obligated, not morally obligated because it would be operating completely and solely by physical forces. When a machine's actions are completely determined by physical forces, the moral intent cannot be known because the entire operation of the machine is based on coercion.

Yet we both know intuitively that I am morally obligated. Why?

Cordially,
