Abstract
This paper examines the potential limitations of professional wisdom alongside those of society more generally with respect to upholding the well-being of vulnerable and marginalized people. It presents the dangers, referring to four well-documented illustrations of professional failure, that services and service systems pose when both professionals and society at large do not demonstrate sufficient measures of positive values and ethics to ensure the protection of vulnerable people within care systems. While it argues that reform of service systems and the repair of such breaches are always possible, even such system reform may fail if it is not ultimately guided by wisdom not only from professionals but society itself. Several recent international examples of this wisdom are noted. It sees such wisdom as being located in the inherited values and social ethics of a society and the power of these to guide human conduct in the face of the profound and ongoing limitations of human nature
