Here is the rest of that article 70 of "Evangelium Vitae". This is also excellent.
Democracy cannot be idolized to the point of making it a substitute for morality or a panacea for immorality. Fundamentally, democracy is a "system" and as such is a means and not an end. Its "moral" value is not automatic, but depends on conformity to the moral law to which it, like every other form of human behaviour, must be subject: in other words, its morality depends on the morality of the ends which it pursues and of the means which it employs. If today we see an almost universal consensus with regard to the value of democracy, this is to be considered a positive "sign of the times", as the Church's Magisterium has frequently noted. 88 But the value of democracy stands or falls with the values which it embodies and promotes. Of course, values such as the dignity of every human person, respect for inviolable and inalienable human rights, and the adoption of the "common good" as the end and criterion regulating political life are certainly fundamental and not to be ignored.
The basis of these values cannot be provisional and changeable "majority" opinions, but only the acknowledgment of an objective moral law which, as the "natural law" written in the human heart, is the obligatory point of reference for civil law itself. If, as a result of a tragic obscuring of the collective conscience, an attitude of scepticism were to succeed in bringing into question even the fundamental principles of the moral law, the democratic system itself would be shaken in its foundations, and would be reduced to a mere mechanism for regulating different and opposing interests on a purely empirical basis. 89
Some might think that even this function, in the absence of anything better, should be valued for the sake of peace in society. While one acknowledges some element of truth in this point of view, it is easy to see that without an objective moral grounding not even democracy is capable of ensuring a stable peace, especially since peace which is not built upon the values of the dignity of every individual and of solidarity between all people frequently proves to be illusory. Even in participatory systems of government, the regulation of interests often occurs to the advantage of the most powerful, since they are the ones most capable of manoeuvering not only the levers of power but also of shaping the formation of consensus. In such a situation, democracy easily becomes an empty word.
