Kant's Grundlegung zur Metaphysik der Sitten is popular as an introduction into his philosophy and into fundamental ethics in general. Its third chapter is, nevertheless, a notoriously difficult text. According to many interpreters, it raises questions rather than answering them. This article tries to answer some questions which often remain unclear even in the secondary literature: how is the logical structure of the chapter; what exactly is the synthetic character of the categorical imperative; how does freedom function as the third, (...) connecting term in this synthesis; what is the relationship between questions concerning the possibility and the validity of the categorical imperative? In his own words, Kant wants to give here 'a deduction of the principle of morality' but also of the concept of freedom. The double use of the term 'deduction' needs an accurate interpretation. One thesis of the article is that the deduction of freedom must not be identified with the problematic deduction of the categorical imperative. The deduction of the concept of freedom has a more modest function within the proof of the possibility of the categorical imperative. This means that the question concerning the proof of its validity is still open; but the very idea that such a proof is neither possible nor necessary evokes already the notion of the factum der Vernunft.

Inleiding tot de wijsgerige ethiek, met bijzondere aandacht voor het kantiaanse perspectief.

The example of a political leader who has to decide whether he would allow the torture of a suspect in order to get information about a ticking bomb has become notorious in ethical discussions concerning the tension between moral principles and political necessity. The relation between these notions must be made as clear as possible before a sincere moral evaluation of ticking bomb situations can be given. The first section of this article considers whether the concept of political obligation is (...) different from moral and legal obligations or whether it is a special kind of moral obligation. In the second section, the idea that the dirty hands problem confronts us with the ambiguities of moral life is rejected because it would imply an untenable moral paradox. The thesis that is developed is, namely, if there is such a thing as political necessity, it must be some form of moral obligation. The third section analyses the concept of political necessity and concludes that it cannot overrule basic moral principles and that the international legal prohibition of torture must be considered to be a categorical imperative. In the last section, these ideas concerning political and moral necessity are brought in against the defence of torture, which should be tolerated in the ‘War on Terror’. There it will be argued that the use of the ticking bomb argument not only supports a highly hypocrite political practice but is also deceptive as a moral and political argument. (shrink)
