This article contends that certain types of Autonomous Weapons Systems (AWS) are susceptible to Hume’s Law. Hume’s Law highlights the seeming impossibility of deriving moral judgments, if not all evaluative ones, from purely factual premises. If autonomous weapons make use of factual data from their environments to carry out specific actions, then justifying their ethical decisions may prove to be intractable in light of the said problem. In this article, Hume’s original formulation of the no-ought-from-is thesis is evaluated in relation (...) to the dominant views regarding it (viz., moral non-descriptivism and moral descriptivism). Citing the objections raised against these views, it is claimed that, if there is no clear-cut solution to Hume’s is-ought problem that presently exists, then the task of grounding the moral judgements of AWS would still be left unaccounted for.

One of the primary, if not most critical, difficulties in the design and implementation of autonomous systems is the black-boxed nature of the decision-making structures and logical pathways. How human values are embodied and actualised in situ may ultimately prove to be harmful if not outright recalcitrant. For this reason, the values of stakeholders become of particular significance given the risks posed by opaque structures of intelligent agents (IAs). This paper explores how decision matrix algorithms, via the belief-desire-intention model for (...) autonomous vehicles, can be designed to minimize the risks of opaque architectures. Primarily through an explicit orientation towards designing for the values of explainability and verifiability. In doing so, this research adopts the Value Sensitive Design (VSD) approach as a principled framework for the incorporation of such values within design. VSD is recognized as a potential starting point that offers a systematic way for engineering teams to formally incorporate existing technical solutions within ethical design, while simultaneously remaining pliable to emerging issues and needs. It is concluded that the VSD methodology offers at least a strong enough foundation from which designers can begin to anticipate design needs and formulate salient design flows that can be adapted to the changing ethical landscapes required for utilisation in autonomous vehicles.

ABSTRACTAutonomous weapons systems pose many challenges in complex battlefield environments. Previous discussions of them have largely focused on technological or policy issues. In contrast, we focus here on the challenge of trust in an AWS. One type of human trust depends only on judgments about the predictability or reliability of the trustee, and so are suitable for all manner of artifacts. However, AWSs that are worthy of the descriptor “autonomous” will not exhibit the required strong predictability in the complex, changing (...) contexts of war. Instead, warfighters need to develop deeper, interpersonal trust that is grounded in understanding the values, beliefs, and dispositions of the AWS. Current acquisition, training, and deployment processes preclude the development of such trust, and so there are currently no routes for a warfighter to develop trust in an AWS. We thus survey three possible changes to current practices in order to facilitate the type of deep trust that is required for appropri... (shrink)

Lethal Autonomous Weapons (LAWs) are robotic weapons systems, primarily of value to the military, that could engage in offensive or defensive actions without human intervention. This paper assesses and engages the current arguments for and against the use of LAWs through the lens of achieving more ethical warfare. Specific interest is given particularly to ethical LAWs, which are artificially intelligent weapons systems that make decisions within the bounds of their ethics-based code. To ensure that a wide, but not exhaustive, survey (...) of the implications of employing such ethical devices to replace humans in warfare is taken into account, this paper will engage on matters related to current scholarship on the rejection or acceptance of LAWs—including contemporary technological shortcomings of LAWs to differentiate between targets and the behavioral and psychological volatility of humans—and current and proposed regulatory infrastructures for developing and using such devices. After careful consideration of these factors, this paper will conclude that only ethical LAWs should be used to replace human involvement in war, and, by extension of their consistent abilities, should remove humans from war until a more formidable discovery is made in conducting ethical warfare.

ABSTRACTTwo categories of ethical questions surrounding military autonomous systems are discussed in this article. The first category concerns ethical issues regarding the use of military autonomous systems in the air and in the water. These issues are systematized with the Laws of Armed Conflict as a backdrop. The second category concerns whether autonomous systems may affect the ethical interpretation of LOAC. It is argued that some terms in LOAC are vague and can be interpreted differently depending on which ethical normative (...) theory is used, which may increase with autonomous systems. The impact of Unmanned Aerial Vehicles on the laws of war will be discussed and compared to Maritime Autonomous Systems. The conclusion is that there is need for revisions of LOAC regarding autonomous systems, and that the greatest ethically relevant difference between UAVs and MAS has to do with issues connected to jus ad bellum – particularly lowering the threshold for starting war – but also the sen...

The purpose of this article is to provide a multi-perspective examination of one of the most important contemporary security issues: weaponized, and especially lethal, artificial intelligence. This technology is increasingly associated with the approaching dramatic change in the nature of warfare. What becomes particularly important and evermore intensely contested is how it becomes embedded with and concurrently impacts two social structures: ethics and law. While there has not been a global regime banning this technology, regulatory attempts at establishing a ban (...) have intensified along with acts of resistance and blocking coalitions. This article aims to reflect on the prospects and limitations, as well as the ethical and legal intensity, of the emerging regulatory framework. To allow for such an investigation, a power-analytical approach to studying international security regimes is utilized. (shrink)
