A leading developmental psychologist proposes an evolutionary pathway to human psychological agency.Nature cannot build organisms biologically prepared for every contingency they might possibly encounter. Instead, Nature builds some organisms to function as feedback control systems that pursue goals, make informed behavioral decisions about how best to pursue those goals in the current situation, and then monitor behavioral execution for effectiveness. Nature builds psychological agents. In a bold new theoretical proposal, Michael Tomasello advances a typology of the main forms of psychological agency that emerged on the evolutionary pathway to human beings. Tomasello outlines four main types of psychological agency and describes them in evolutionary order of emergence. First was the goal-directed agency of ancient vertebrates, then came the intentional agency of ancient mammals, followed by the rational agency of ancient great apes, ending finally in the socially normative agency of a

Recent interest in the evolution of the social contract is extended by providing a throughly naturalistic, evolutionary account of the biological underpinnings of a social contract theory of morality. This social contract theory of morality (contractevolism) provides an evolutionary justification of the primacy of a moral principle of maximisation of the opportunities for evolutionary reproductive success (ERS), where maximising opportunities does not entail an obligation on individuals to choose to maximise their ERS. From that primary principle, the moral principles of inclusion, individual sovereignty (liberty) and equality can be derived. The implications of these principles, within contractevolism, are explored through an examination of patriarchy, individual sovereignty and copulatory choices, and overpopulation and extinction. Contractevolism is grounded in evolutionary dynamics that resulted in humans and human societies. The most important behavioural consequences of evolution

Quack, moo and neigh along to this riotous cumulative song that features animals of all shapes and sizes. Inspired by a folk tale from Chile, this classic Barefoot Books singalong story introduces children to animals and their babies, and teaches how to count up to 16 in multiples of 2.

Pratt investigates the potential erosion of prohibiting assassination, torture, and mercenarism during the US's War on Terrorism. In examining the emergence and history of the US's targeted killing programme, detention and interrogation programme, and employment of armed contractors in warzones, he proposes that a 'normative transformation' has occurred, which has changed the meaning and content of these prohibitions, even though they still exist. Drawing on pragmatist philosophy, practice theory, and relational sociology, this book develops a new theory of normativity and institutional change, and offers new data about the decisions and activities of security practitioners. It is both a critical and constructive addition to the current literature on norm change, and addresses enduring debates about the role of culture and ethical judgement in the use of force. It will appeal to students and scholars of foreign and defence policy, international relations theory, international security,
