Negligence, defined as the failure to exercise the care a reasonable person would in similar circumstances, forms a cornerstone of tort law, encompassing harm resulting from unmet duties of care. Legal scholars such as Sir John W. Salmond distinguished between unintentional and deliberate negligence, emphasizing that the latter involves a conscious disregard for foreseeable risks, while R. Vashon Rogers characterized negligence as a lack of attentiveness in professional responsibilities.
Benjamin Nathan Cardozo’s jurisprudence emphasized the objective standard of a "reasonable person," balancing personal intent with societal expectations. These viewpoints highlight negligence’s dual nature: a failure to meet a duty that leads to predictable harm, requiring evidence of causation and injury. The concept remains rooted in the relationship between legal responsibility and the predictability of outcomes, as demonstrated by judicial rulings and academic discussions.
