other totalitarian regimes, thereby doing a great service to justice and to humanity as a whole. For these people, it was indisputably evident that the law in force was actually unlawful. Yet when it comes to the decisions of a democratic politician, the question of what now corresponds to the law of truth, what is actually right and may be enacted as law, is less obvious.

In terms of the underlying anthropological issues, what is right and may be given the force of law is in no way simply self-evident today. The question of how to recognize what is truly right and thus to serve justice when framing laws has never been simple, and today in view of the vast extent of our knowledge and our capacity, it has become still harder. How do we recognize what is right?

In history, systems of law have almost always been based on religion: decisions regarding what was to be lawful among men were taken with reference to the divinity. Unlike other great religions, Christianity has never proposed a revealed body of law to the State and to society, that is to say a juridical order derived from revelation. Instead, it has pointed to nature and reason as the true sources of law - and to the harmony of objective and subjective reason, which naturally presupposes that both spheres are rooted in the creative reason of God.

Christian theologians thereby aligned themselves with a philosophical and juridical movement that began to take shape in the second century B.C. In the first half of that century, the social natural law developed by the Stoic philosophers came into contact with leading teachers of Roman law. Through this encounter, the juridical culture of the West was born, which was and is of key significance for the juridical culture of mankind.

This pre-Christian marriage between law and philosophy opened up the path that led via the Christian Middle Ages and the juridical developments of the Age of Enlightenment all the way to the Declaration of Human Rights and to our German Basic Law of 1949, with which our nation committed itself to "inviolable and inalienable human rights as the foundation of every human community, and of peace and justice in the world".

For the development of law and for the development of humanity, it was highly significant that Christian theologians aligned themselves against the religious law associated with polytheism and on the side of philosophy, and that they acknowledged reason and nature in their interrelation as the universally valid source of law. This step had already been taken by Saint Paul in the Letter to the Romans, when he said:

"When Gentiles who have not the Law [the Torah of Israel] do by nature what the law requires, they are a law to themselves ... they show that what the law requires is written on their hearts, while their conscience also bears witness ..." (Rom 2:14f.). Here we see the two fundamental concepts of nature and conscience, where conscience is nothing other than Solomon's listening heart, reason that is open to the language of being.

If this seemed to offer a clear explanation of the foundations of legislation up to the time of the Enlightenment, up to the time of the Declaration on Human Rights after the Second World War and the framing of our Basic Law, there has been a dramatic shift in the situation in the last half-century. The idea of natural law is today viewed as a specifically Catholic doctrine, not worth bringing into the discussion in a non-Catholic environment, so that one feels almost ashamed even to mention the term. ...

Where positivist reason considers itself the only sufficient culture and banishes all other cultural realities to the status of subcultures, it diminishes man, indeed it threatens his humanity. I say this with Europe specifically in mind, where there are concerted efforts to recognize only positivism as a common culture and a common basis for law-making, so that all the other insights and values of our culture are reduced to the level of subculture, with the result that Europe vis-à-vis other world cultures is left in a state of culturelessness and at the same time extremist and radical movements emerge to fill the vacuum.

In its self-proclaimed exclusivity, the positivist reason which recognizes nothing beyond mere functionality resembles a concrete bunker with no windows, in which we ourselves provide lighting and atmospheric conditions, being no longer willing to obtain either from God's wide world. And yet we cannot hide from ourselves the fact that even in this artificial world, we are still covertly drawing upon God's raw materials, which we refashion into our own products. The windows must be flung open again, we must see the wide world, the sky and the earth once more and learn to make proper use of all this.

But how are we to do this? How do we find our way out into the wide world, into the big picture? How can reason rediscover its true greatness, without being sidetracked into irrationality? How can nature reassert itself in its true depth, with all its demands, with all its directives? I would like to recall one of the developments in recent political history, hoping that I will neither be misunderstood, nor provoke too many one-sided polemics.

I would say that the emergence of the ecological movement in German politics since the 1970s, while it has not exactly flung open the windows, nevertheless was and continues to be a cry for fresh air which must not be ignored or pushed aside, just because too much of it is seen to be irrational. Young people had come to realize that something is wrong in our relationship with nature, that matter is not just raw material for us to shape at will, but that the earth has a dignity of its own and that we must follow its directives.

In saying this, I am clearly not promoting any particular political party - nothing could be further from my mind. If something is wrong in our relationship with reality, then we must all reflect seriously on the whole situation and we are all prompted to question the very foundations of our culture. Allow me to dwell a little longer on this point. The importance of ecology is no longer disputed. We must listen to the language of nature and we must answer accordingly.

Yet I would like to underline a further point that is still largely disregarded, today as in the past: there is also an ecology of man. Man too has a nature that he must respect and that he cannot manipulate at will. Man is not merely self-creating freedom. Man does not create himself. He is intellect and will, but he is also nature, and his will is rightly ordered if he listens to his nature, respects it and accepts himself for who he is, as one who did not create himself. In this way, and in no other, is true human freedom fulfilled....

The culture of Europe arose from the encounter between Jerusalem, Athens and Rome - from the encounter between Israel's monotheism, the philosophical reason of the Greeks and Roman law. This three-way encounter has shaped the inner identity of Europe. In the awareness of man's responsibility before God and in the acknowledgment of the inviolable dignity of every single human person, it has established criteria of law: it is these criteria that we are called to defend at this moment in our history.

As he assumed the mantle of office, the young King Solomon was invited to make a request. How would it be if we, the law-makers of today, were invited to make a request? What would we ask for? I think that, even today, there is ultimately nothing else we could wish for but a listening heart - the capacity to discern between good and evil, and thus to establish true law, to serve justice and peace. Thank you for your attention!"
