We discuss the demandingness of Kant’s ethics. Whilst previous discussions of this issue focused on imperfect duties, our first aim is to show that Kantian demandingness is especially salient in the class of perfect duties. Our second aim is to introduce a fine-grained picture of demandingness by distinguishing between different possible components of a moral theory which can lead to demandingness: a required process of decision making, overridingness and the stringent content of demands, due to a standpoint of moral purity. This distinction allows a specification of the sources of demandingness in Kant. The most characteristically Kantian form of demandingness springs from overridingness and purity and comes as a constant threat that an agent might find herself in a situation in which, due to no fault of her own, she is required to sacrifice everything for little to no non-moral goods. Our third aim is to discuss whether Kant has the resources to reply to those who criticize his ethics based on its demandingness. For this purpose we discuss Kant’s notion of “rationalizing” in the context of various types of current conceptions of demandingness and calls for moderate ethical theories

Ido Geiger's paper ‘What it is the Use of the Universal Law Formula of the Categorical Imperative?’ is part of a growing trend in Kant scholarship, which stresses the significance of the rational competence of ordinary human beings. I argue that this approach needs to take into account that the common agent is an active reasoner who has the means to find out what she ought to do. The purpose of my paper is to show how universality already figures in the active reasoning of pre-theoretical agents in the form of a common universalization test. I present textual evidence for this test, and argue that this conception does not present pre-theoretical moral cognition in an overly intellectualistic or mechanistic way. Finally, I discuss how, on the pre-theoretical level, universalization relates to humanity or a rational agent's special status. Universalization is present to common agents in the form of procedures or questions that we ask ourselves, humanity as an awareness of certain particularly blatant violat..

Nach Parfit konvergieren die systematisch stärksten Versionen von Kantianismus, Regel-Konsequentialismus und Kontraktualismus in einer Triple Theory. Ich konzentriere mich auf eine der zentralen Schwierigkeiten, Kantianismus und Konsequentialismus zusammenzubringen: die Rolle von Zustimmung, welche ihren deutlichsten Ausdruck in Kants Zweck-an-sich-Formel findet. Ich zeige zunächst, wie die Einführung unparteilicher, nichtmoralischer Gründe, auf der viel Gewicht in Parfits Zustimmungsprinzip liegt, in einigen Fällen die Zweck-an-sich-Formel zu dem intuitiv richtigen Ergebnis führen kann. Anschließend wende ich mich kritisch gegen Parfit. Ich diskutiere zwei Einwände gegen Parfits Zustimmungsprinzip: Das Zustimmungsprinzip ist unterbestimmt und daher nicht relevant für die Fälle, die Kantianismus und Konsequentialismus unterscheiden. Zudem lässt das Zustimmungsprinzip, wie Parfit es versteht, mehr Instrumentalisierung zu, als Parfit selbst bereit ist einzuräumen.

There is a consensus that Kant's aim in the Groundwork is to clarify, systematize and vindicate the common conception of morality. Philosophical theory hence serves a restorative function. It can strengthen agents' motivation, protect against self-deception and correct misunderstandings produced by uncritical moral theory. In this paper, I argue that Kant also corrects the common perspective and that Kant's Groundwork shows in which senses the common perspective, even considered apart from its propensity to self-deception and without being influenced by misleading theory, is deficient. Critical practical philosophy needs to set right agents about the stringency of some of their duties, and agents need to be made aware that they have certain other duties. I discuss how Kant corrects the common agent's notion of the stringency of the duty to not make false promises and how Kant corrects the common agent's notion of duties to self. I finally discuss how his critical practical philosophy can become popular and achieve the correction of the common perspective. I stress the role of education informed by philosophical theory for this and contrast it with so called ‘popular philosophy’.

The author defends Conciliationism as a response to peer-disagreement in ethics against a prominent objection: if in cases of peer-disagreement we have to move our credences towards those of our dissenting peers, then we have to adopt scepticism in fields where disagreement between peers abounds. For this objection, the case of ethics is particularly worrisome. The author argues that the objection from scepticism is based on a highly idealised notion of an epistemic peer. In cases of disagreement about ethical issues, it is often unknown to us what another person counts as her evidence, since one’s notions of what counts as evidence and what weight to attach to different forms of evidence are impacted by one’s global outlook. Being aware of what an agent considers as evidence requires familiarity with that agent’s global outlook. This introduces two constraints on epistemic peerhood in cases of disagreement about ethics: an epistemic constraint, and a factual constraint.

I discuss two puzzling and neglected passages in the Critique of Practical Reason, namely, V:92 and V:163. In these passages Kant claims that practical philosophers should follow the paradigm of the chemist and conduct experiments on common human reason. I explain Kant’s conception of the chemical experiment, provide a detailed interpretation of the two passages in question, and conclude by applying the structure of the chemical experiment to the Analytic of the Critique of Practical Reason. Chemical experiments as a model of ethics should be understood as a method of confirming that a philosophical theory systematizes and defends ideas that ordinary rational agents are already committed to.

In my thesis I explain why the common, pre-theoretical understanding of morality is an important part of Kant’s ethics, and I critically evaluate what the strengths and weaknesses are of doing ethics with the common perspective as a point of reference. In chapter 1, I discuss the significance of common rational capacities for the deduction in Groundwork III as well as for the Fact of Reason. Attention to the fundamental role of common rational capacities in the Second Critique reveals that Kant intends to provide further warrant for the Fact than its introspective self-evidence. In chapter 2, I discuss what it means for a rational agent to be endowed with common rational capacities. The agent has everything she needs to reason on her own about what she ought to do and act from rational judgements. Furthermore, I critically evaluate Kant’s claim that his ethics spells out fundamental, pre-theoretical convictions. In chapter 3, I discuss Kant’s conception of rationalizing. I analyse rationalizing as a process of self-deception in which an agent tries to justify or excuse violations of the moral law. This can lead to loss of the reliable use of common rational capacities. I discuss what help critical practical philosophy and moral education can afford against rationalizing. In chapter 4, I argue that Kant saw dialogical engagement with ordinary agents as an important way of obtaining data concerning the correct starting point of practical philosophy. Kant demands that whatever we get from dialog and observation has to be isolated from its contingent elements. I conclude that the main problem for Kant’s method is how we can, on the one hand, exclude non-rational content, and, on the other hand, be open to what other agents actually have to say about morality.
