Like most trends, at the beginning it's driven by fundamentals, at some point speculation takes over. What the wise man does in the beginning, the fool does in the end.
Heaven is for thee too high To know what passes there; be lowly wise. Think only what concerns thee and thy being; Dream not of other worlds, what creatures there Live, in what state, condition, or degree, Contented that thus far hath been revealed.
There are errors which no wise man will treat with rudeness while there is a probability that they may be the refraction of some great truth still below the horizon.
A prince who is not himself wise cannot be wisely advised. . . . Good advice depends on the shrewdness of the prince who seeks it, and not the shrewdness of the prince on good advice.
The fool sees naught but folly; and the madman only madness. Yesterday I asked a foolish man to count the fools among us. He laughed and said, "This is too hard a thing to do, and it will take too long. Were it not better to count only the wise?"
Although God is all powerful, He is unable to give more; though supremely wise, He knows not how to give more; though vastly rich, He has not more to give.
One should follow a man of wisdom who rebukes one for one's faults, as one would follow a guide to some buried treasure. To one who follows such a wise man, it will be an advantage and not a disadvantage.
Times are changed with him who marries; there are no more by-path meadows, where you may innocently linger, but the road lies long and straight and dusty to the grave. Idleness, which is often becoming and even wise in the bachelor, begins to wear a different aspect when you have a wife to support.
All our thoughts and concepts are called up by sense-experiences and have a meaning only in reference to these sense-experiences. On the other hand, however, they are products of the spontaneous activity of our minds; they are thus in no wise logical consequences of the contents of these sense-experiences. If, therefore, we wish to grasp the essence of a complex of abstract notions we must for the one part investigate the mutual relationships between the concepts and the assertions made about them; for the other, we must investigate how they are related to the experiences.
She marking them begins a wailing note And sings extemporally a woeful ditty How love makes young men thrall and old men dote How love is wise in folly, foolish-witty Her heavy anthem still concludes in woe, And still the choir of echoes answer so.
