to which it is joined, and from the perceptions, from which it has originated. It is of an entirely different nature from these impressions of the senses. Yet it is able to take up into itself all the results of perception, and give them back again unchanged and undiminished after the longest period of time; thus alone does experience arise. But the concept preserves, not what is perceived nor what is then felt, but only what is essential in these, in an entirely altered form, and yet as an adequate representative of them. Just as flowers cannot be preserved, but their ethereal oil, their essence, with the same smell and the same virtues, can be. The action that has been guided by correct conceptions will, in the result, coincide with the real object aimed at. We may judge of the inestimable value of conceptions, and consequently of the reason, if we glance for a moment at the infinite multitude and variety of the things and conditions that coexist and succeed each other, and then consider that speech and writing (the signs of conceptions) are capable of affording us accurate information as to everything and every relation when and wherever it may have been; for comparatively few conceptions can contain and represent an infinite number of things and conditions. In our own reflection abstraction is a throwing off of useless baggage for the sake of more easily handling the knowledge which is to be compared, and has therefore to be turned about in all directions. We allow much that is unessential, and therefore only confusing, to fall away from the real things, and work with few but essential determinations thought in the abstract. But just because general conceptions are only formed by thinking away and leaving out existing qualities, and are therefore the emptier the more general they are, the use of this procedure is confined to the working up of knowledge which we have already acquired. This working up includes the drawing of conclusions from premisses contained in our knowledge. New insight, on the contrary, can only be obtained by the help
