Recent advancements in neuroscientific techniques have allowed us to make huge progress in our understanding of memories, and in turn has paved the way for new memory modification technologies (MMTs) that can modulate memories with a degree of precision, which was not previously possible. With advancements in such techniques, new and critical ethical questions have emerged. Understanding and framing these ethical questions within the current philosophical theories is crucial in order to systematically examine them as we translate these techniques to the clinic.
In this paper, we discuss the ethical implications of modern neuroscience techniques that aim to disrupt or enhance memories. We attempt to frame the MMTs in the context of existing ethical philosophical theories to provide a cohesive analysis of the myriad of ethical quagmires that might emerge from such technologies. We argue the application of Aristotle's Golden Mean and multiple accounts of authenticity are useful in approaching the ethical questions surrounding MMTs. We then propose a framework in which ethical considerations can be systematically examined. Lastly, we provide caveats and considerations for the use of this framework. Overall, we provide a practical approach for the ethical use of MMTs depending on the situation.
While at face value, our model appears to put severe limitations on the application of MMTs, we are not completely opposed to their use, but rather our framework guides the agent to consider the implications before making any decisions. Most importantly, we argue that the use of MMTs does not reduce the responsibility of the initial decision, and the agent must accept the post-MMT self as the new "true self" regardless of the outcome. As the developmental trajectory of MMTs suggests we are getting closer to practical clinical applications, ethical concerns across a wide range of disciplines need to be addressed to develop best strategies and policies when dealing with MMTs. If this can be achieved, we believe the ethical use of MMTs is not only possible but would also be of tremendous benefit to many people suffering from memory-related mental disorders.
神经科学技术的最新进展使我们在理解记忆方面取得了巨大进步,进而为新的记忆修改技术(MMTs)铺平了道路,这些技术能够以前所未有的精度调节记忆。随着此类技术的进步,新的关键伦理问题出现了。在当前哲学理论的框架内理解和阐释这些伦理问题,对于我们将这些技术转化为临床应用时系统地审视它们至关重要。
在本文中,我们讨论旨在干扰或增强记忆的现代神经科学技术的伦理影响。我们试图将记忆修改技术置于现有的伦理哲学理论背景中,以便对这些技术可能引发的众多伦理困境进行连贯分析。我们认为,应用亚里士多德的中庸之道以及多种真实性的观点,有助于探讨围绕记忆修改技术的伦理问题。然后,我们提出一个可以系统审视伦理考量的框架。最后,我们对该框架的使用提出了注意事项和考量因素。总体而言,我们根据具体情况为记忆修改技术的伦理使用提供了一种实用方法。
虽然从表面上看,我们的模型似乎对记忆修改技术的应用施加了严格限制,但我们并非完全反对其使用,而是我们的框架引导使用者在做出任何决定之前考虑其影响。最重要的是,我们认为使用记忆修改技术并不会减轻最初决策的责任,无论结果如何,使用者都必须接受记忆修改技术应用后的自我为新的“真实自我”。随着记忆修改技术的发展轨迹表明我们正越来越接近实际临床应用,在处理记忆修改技术时,需要解决广泛学科领域的伦理问题,以制定最佳策略和政策。如果能够做到这一点,我们相信记忆修改技术的伦理使用不仅是可能的,而且对许多患有与记忆相关精神障碍的人将大有裨益。
