This paper delves into the intricate relationship between euthanasia and the perpetual pendulum concept, which challenges conventional linear understandings of time and legal principles. Examining euthanasia through the perpetual pendulum concept, inspired by Deleuze and Guattari’s rhizome theory, underscores that the acceptance or prohibition of euthanasia is deeply intertwined with evolving societal values and conceptual frameworks. It advocates for adaptable legal interpretations and an acknowledgment of the relative nature of time, allowing for the reevaluation and reinterpretation of legal principles in response to changing perspectives. The legal landscape of euthanasia in Australia, with varying state laws and potential conflicts with federal statutes, serves as a compelling case study. It emphasizes the ongoing need for discussion, adaptation, and ethical introspection to balance individual autonomy with broader legal and ethical considerations in the context of end-of-life care.
