Wealth is like sea-water; the more we drink, the thirstier we become. - Arthur Schopenhauer

The result of this mental dullness is that inner vacuity and emptiness that is stamped on innumerable faces and also betrays itself in a constant and lively attention to all events in the external world, even the most trivial. This vacuity is the real source of boredom and always craves for external excitement in order to set the mind and spirits in motion through something. Therefore in the choice thereof it is not fastidious, as is testified by the miserable and wretched pastimes to which people have recourse. … The principal result of this inner vacuity is the craze for society, diversion, amusement, and luxury of every kind which lead many to extravagance and so to misery. Nothing protects us so surely from this wrong turning as inner wealth, the wealth of the mind, for the more eminent it becomes, the less room does it leave for boredom. The inexhaustible activity of ideas, their constantly renewed play with the manifold phenomena of the inner and outer worlds, the power and urge always to make different combinations of them, all these put the eminent mind, apart from moments of relaxation, quite beyond the reach of boredom.

And now that I have allowed myself the jest to which in this two-sided life hardly any page can be too serious to grant a place, I part with the book with deep seriousness, in the sure hope that sooner or later it will reach those to whom alone it can be addressed; and for the rest, patiently resigned that the same fate should, in full measure, befall it, that in all ages has, to some extent, befallen all knowledge, and especially the weightiest knowledge of the truth, to which only a brief triumph is allotted between the two long periods in which it is condemned as paradoxical or disparaged as trivial. The former fate is also wont to befall its author. But life is short, and truth works far and lives long: let us speak the truth.

When the Church says that, in the dogmas of religion, reason is totally incompetent and blind, and its use to be reprehended, this really attests the fact that these dogmas are allegorical in their nature, and are not to be judged by the standard which reason, taking all things sensu proprio, can alone apply. Now the absurdities of a dogma are just the mark and sign of what is allegorical and mythical in it. In the case under consideration, however, the absurdities spring from the fact that two such heterogeneous doctrines as those of the Old and New Testaments had to be combined. The great allegory was of gradual growth. Suggested by external and adventitious circumstances, it was developed by the interpretation put upon them, an interpretation in quiet touch with certain deep-lying truths only half realised. The allegory was finally completed by Augustine, who penetrated deepest into its meaning, and so was able to conceive it as a systematic whole and supply its defects.
