The fundament upon which all our knowledge and learning rests is the inexplicable. - Arthur Schopenhauer

Life presents itself as a continual deception, in small matters as well as in great. If it has promised, it does not keep its word, unless to show how little desirable the desired object was; hence we are deluded now by hope, now by what was hoped for. If it has given, it did so in order to take. The enchantment of distance shows us paradises that vanish like optical illusions, when we have allowed ourselves to be fooled by them. Accordingly, happiness lies always in the future, or else in the past, and the present may be compared to a small dark cloud driven by the wind over the sunny plain; in front of and behind the cloud everything is bright, only it itself always casts a shadow. Consequently, the present is always inadequate, but the future is uncertain, and the past irrecoverable.

A spring never free from the pressure of some foreign body at last loses its elasticity; and so does the mind if other people’s thoughts are constantly forced upon it.

When we read, another person thinks for us: we merely repeat his mental process. It is the same as the pupil, in learning to write, following with his pen the lines that have been pencilled by the teacher. Accordingly, in reading, the work of thinking is, for the greater part, done for us. This is why we are consciously relieved when we turn to reading after being occupied with our own thoughts. But, in reading, our head is, however, really only the arena of some one else's thoughts. And so it happens that the person who reads a great deal — that is to say, almost the whole day, and recreates himself by spending the intervals in thoughtless diversion, gradually loses the ability to think for himself; just as a man who is always riding at last forgets how to walk. Such, however, is the case with many men of learning: they have read themselves stupid. For to read in every spare moment, and to read constantly, is more paralysing to the mind than constant manual work...
