text: And virtue herself will have the same effect upon you, of making you admire her and yet hope to attain her. In my own case, at any rate the very contemplation of wisdom takes much of my time; I gaze upon her with bewilderment, just as I sometimes gaze upon the firmament itself, which I often behold as if I saw it for the first time. Hence I worship the discoveries of wisdom and their discoverers; to enter, as it were, into the inheritance of many predecessors is a delight. It was for me that they laid up this treasure; it was for me that they toiled. But we should play the part of a careful householder; we should increase what we have inherited. This inheritance shall pass from me to my descendants larger than before. Much still remains to do, and much will always remain, and he who shall be born a thousand ages hence will not be barred from his opportunity of adding something further. But even if the old masters have discovered everything, one thing will be always new, – the application and the scientific study and classification of the discoveries made by others. Assume that prescriptions have been handed down to us for the healing of the eyes; there is no need of my searching for others in addition; but for all that, these prescriptions must be adapted to the particular disease and to the particular stage of the disease. Use this prescription to relieve granulation of the eyelids, that to reduce the swelling of the lids, this to prevent sudden pain or a rush of tears, that to sharpen the vision. Then compound these several prescriptions, watch for the right time of their application, and apply the proper treatment in each case.
