There is a need for acknowledging how commitment to kill can be maintained by being the killer personally. This appears to be the ability for the prevention of killing irrespective of who is the actual killer. Personal identity does not help in clarifying how there must be comparison of two different consideration (Mill 120). Thus, there is no clarity for comparing the partially weighted commitment of Jim to not kill individuals. Second, there is a need for clarifying how much the commitment of Jim to not kill people is absolutely not a commitment to not kill people. Personal identity involves a difficult time to decide what is to be done in the case of Jim for two basic reasons. First, personal identity will not involve a flat rejection of the calculus of utilitarianism, instead, it ends up complicating it (Mill 20). The key suggestion is that a provided agent will not be considering the effect of her action in the entire happiness, while considering the relationship of her action to moral identity and her own project. Virtually, two level utilitarianism tends to be synthesizing the opposed doctrines of rule utilitarianism and act utilitarianism.
It has been stated by act utilitarianism that in each and every case, the one is morally right for the production of maximum pleasure. On the other hand, it has been stated by rule utilitarianism that the action which is morally right is the one as per a moral rule. There is general observance for the creation of major happiness (Mill 100). With respect to utilitarianism at two levels, there is likening of act utilitarianism at the crucial level of moral thinking and rule utilitarianism to the level of intuition. Considering another hypothetical example, there is an experience machine, namely Superduper neurophysiologists providing any experience as per the desire set. This helps in stimulating the brain so that one will think and feel one is writing up a huge novel, or have made a friend, or have read an interesting book. The entire time, one will float in a tank with the attachment of electrodes across the brain. Should one consider plugging within the machine for entire life, preprogramming their experiences of life, can depict the undermined form of utilitarianism.
