and by the relation it bears to experience and to desire.
The ideal has the same relation to given demands that the reality has to given perceptions. In the face of the ideal, particular demands forfeit their authority and the goods to which a particular being may aspire cease to be absolute; nay, the satisfaction of desire comes to appear an indifferent or unholy thing when compared or opposed to the ideal to be realised. So, precisely, in perception, flying impressions come to be regarded as illusory when contrasted with a stable conception of reality. Yet of course flying impressions are the only material out of which that conception can be formed. Life itself is a flying impression, and had we no personal and instant experience, importuning us at each successive moment, we should have no occasion to ask for a reality at all, and no materials out of which to construct so gratuitous an idea. In the same way present demands are the only materials and occasions for any ideal: without demands the ideal would have no locus standi or foothold in the world, no power, no charm, and no prerogative. If the ideal can confront particular desires and put them to shame, that happens only because the ideal is the object of a more profound and voluminous desire and embodies the good which they blindly and perhaps deviously pursue. Demands could not be misdirected, goods sought could not be false, if
