Undoubtedly the bad conscience is an illness, but an illness like pregnancy is an illness. If we search out the conditions under which this illness reaches its most terrible and sublime zenith, we shall see what really first brought about its entry into the world. But to do this we must take a long breath, and we must first of all go back once again to an earlier point of view. The relation at civil law of the ower to his creditor (which has already been discussed in detail), has been interpreted once again (and indeed in a manner which historically is exceedingly remarkable and suspicious) into a relationship, which is perhaps more incomprehensible to us moderns than to any other era; that is, into the relationship of the _existing_ generation to its _ancestors_. Within the original tribal association--we are talking of primitive times--each living generation recognises a legal obligation towards the earlier generation, and particularly towards the earliest, which founded the family (and this is something much more than a mere sentimental obligation, the existence of which, during the longest period of man's history, is by no means indisputable). There prevails in them the conviction that it is only thanks to sacrifices and efforts of their ancestors, that the race _persists_ at all--and that this has to be _paid back_ to them by sacrifices and services. Thus is recognised the _owing_ of a debt, which accumulates continually by reason of these ancestors never ceasing in their subsequent life as potent spirits to secure by their power new privileges and advantages to the race. Gratis, perchance? But there is no gratis for that raw and "mean-souled" age. What return can be made?--Sacrifice (at first, nourishment, in its crudest sense), festivals, temples, tributes of veneration, above all, obedience--since all customs are, _quâ_ works of the ancestors, equally their precepts and commands--are the ancestors ever given enough? This suspicion remains and grows: from time to time it extorts a great wholesale ransom, something monstrous in the way of repayment of the creditor (the notorious sacrifice of the first-born, for example, blood, human blood in any case). The _fear_ of ancestors and their power, the consciousness of owing debts to them, necessarily increases, according to this kind of logic, in the exact proportion that the race itself increases, that the race itself becomes more victorious, more independent, more honoured, more feared. This, and not the contrary, is the fact. Each step towards race decay, all disastrous events, all symptoms of degeneration, of approaching disintegration, always _diminish_ the fear of the founders' spirit, and whittle away the idea of his sagacity, providence, and potent presence. Conceive this crude kind of logic carried to its climax: it follows that the ancestors of the _most powerful_ races must, through the growing fear that they exercise on the imaginations, grow themselves into monstrous
