#Latin maxim

• Abuse does not invalidate just use — A fundamental principle in bioethics, pharmacovigilance, and clinical toxicology stating that 'a conclusion from the abuse of a thing to its use is not valid'. In medicine, it means that the prohibition or condemnation of a useful drug or medical treatment (e.g., opioids for severe pain) is not justified simply because some patients or individuals abuse it.
• Begin with the essential — A Latin aphorism adapted in medical methodology and epidemiology meaning 'let us begin with the most important thing' (literally: 'the beginning from Jove/Jupiter'). In clinical diagnosis, toxicology, and epidemiological tracing, the maxim dictates starting the evaluation with the most probable hypothesis, the most dangerous toxin, or the most critically affected vital organ to optimize intervention time and save the patient's life.
• Acta est fabula — A famous Latin aphorism literally translated as 'The play has been acted' or 'The story is finished'. In ancient Roman theater, this structural phrase was pronounced at the end of performances to announce to the audience that the play was over and that they could leave. Existentially, the expression is used metaphorically to mark the end of an important stage, the definitive failure of a plan, or the end of life (historically attributed as the last words of Emperor Augustus).
• Acta, non verba — A Latin aphorism literally translated as 'Deeds, not words'. It is a moral and philosophical maxim used universally to emphasize the importance of concrete actions and tangible results over promises, theoretical statements, or rhetorical speeches. In socio-political and administrative contexts, it serves as a structural call to assume responsibility and demonstrate integrity through real deeds.
• Listen to the other side — A fundamental legal principle derived from Roman law and core to modern judicial systems, translating to 'listen to the other side' or 'let the other party be heard also'; the principle of adversary procedure. It stipulates that no person should be judged or condemned without being given a fair opportunity to respond to the accusations.
