How despotically such a faith deals with all empiricism is worthy of note; with Thales especially one can learn how Philosophy has behaved at all times, when she wanted to get beyond the hedges of experience to her magically attracting goal. On light supports she leaps in advance; hope and divination wing her feet. Calculating reason too, clumsily pants after her and seeks better supports in its attempt to reach that alluring goal, at which its divine companion has already arrived. One sees in imagination two wanderers by a wild forest-stream which carries with it rolling stones; the one, light-footed, leaps over it using the stones and swinging himself upon them ever further and further, though they precipitously sink into the depths behind him. The other stands helpless there most of the time; he has first to build a pathway which will bear his heavy, weary step; sometimes that cannot be done and then no god will help him across the stream. What therefore carries philosophical thinking so quickly to its goal? Does it distinguish itself from calculating and measuring thought only by its more rapid flight through large spaces? No, for a strange illogical power wings the foot of philosophical thinking; and this power is Fancy. Lifted by the latter, philosophical thinking leaps from possibility to possibility, and these for the time being are taken as certainties; and now and then even whilst on the wing it gets hold of certainties. An ingenious presentiment shows them to the flier; demonstrable certainties are divined at a distance to be at this point. Especially powerful is the strength of Fancy in the lightning-like seizing and illuminating of similarities; afterwards reflection applies its standards and models and seeks to substitute the similarities by equalities, that which was seen side by side by causalities. But though this should never be possible, even in the case of Thales the indemonstrable philosophising has yet its value; although all supports are broken when Logic and the rigidity of Empiricism want to get across to the proposition: Everything is water; yet still there is always, after the demolition of the scientific edifice, a remainder, and in this very remainder lies a moving force and as it were the hope of future fertility.
