Two of the most prominent questions in Kant's critical philosophy concern reason. The first, central to his theoretical philosophy, is the unprovable pretensions of reason in earlier “rationalist” philosophers, especially Leibniz and Descartes. The second, central to his practical philosophy, is the subservient role accorded to reason by the British empiricists—above all Hume, who declared, “Reason is wholly inactive, and can never be the source of so active a principle as conscience, or a sense of morals.” Treatise, 3.1.1.11; see also the entry on Rationalism vs. Empiricism .) Thus the titles of two key works: the monumental Critique of Pure Reason, and the Critique of Practical Reason that is middle point of his great trio of moral writings (between the Groundwork of the Metaphysics of Morals and The Metaphysics of Morals).

Hannah Arendt’s (1906-1975) conception of power is entirely distinctive. It is rooted in a political philosophy that celebrates the public realm of freedom that emerges when people act with others as citizens or political equals. For Arendt, power is actualized where people act together to sustain or to change the world they share with one another. Her fundamental claim is this: ‘Power corresponds to the human ability not just to act but to act in concert. Power is never the property of an individual; it belongs to a group and remains in existence only so long as the group keeps together’. This entry offers some background to Arendt’s account, highlights two important contrasts that she makes between power and violence, and then points to her related notion of authority.

This paper considers the often-expressed fear that medical research may use children merely as means, and not respect them as ends in themselves – especially insofar as they are deemed less able to consent than adults. The main focus is on large-scale genetic, socio-medical and epidemiological research. The theoretical starting point of the paper is that to be treated as an end in oneself is to be regarded as – and to act as – a participant in cooperative endeavours. This participatory status is certainly connected with individual authority to consent and dissent; and there is no doubt that consent plays an important role when adults participate in many research projects. However, insofar as consent is located within structures of human cooperation, the authority to consent is not a straightforward privilege. Rather, consent is bound up with responsibility for one's choices and commitment to shared terms of cooperation. Given this understanding, it is argued that consent should not be our principal concern when we involve children in research. This is not because of children's (possible) incompetence to consent as such, but rather because children are still learning how to respect and assess the cooperative terms involved in our institutional lives. Instead, our leading concern should be with the terms regulating their involvement in research. Given suitable safeguards, research is one way in which children may learn what it is to bear responsibilities and to act as an end in oneself – that is, to cooperate with others on reasonable terms and for worthy ends
