A positivist conception of nature as purely functional, as the natural sciences consider it to be, is incapable of producing any bridge to ethics and law, but once again yields only functional answers. The same also applies to reason, according to the positivist understanding that is widely held to be the only genuinely scientific one. Anything that is not verifiable or falsifiable, according to this understanding, does not belong to the realm of reason strictly understood. Hence ethics and religion must be assigned to the subjective field, and they remain extraneous to the realm of reason in the strict sense of the word. Where positivist reason dominates the field to the exclusion of all else – and that is broadly the case in our public mindset – then the classical sources of knowledge for ethics and law are excluded. This is a dramatic situation which affects everyone, and on which a public debate is necessary. Indeed, an essential goal of this address is to issue an urgent invitation to launch one.
