Letters 52.15

I shall postpone this topic for the present; it demands a long and special investigation, to show how the public should be addressed, what indulgences should be allowed to a speaker on a public occasion, and what should be allowed to the crowd itself in the presence of the speaker. There can be no doubt that philosophy has suffered a loss, now that she has exposed her charms for sale. But she can still be viewed in her sanctuary, if her exhibitor is a priest and not a pedlar. Farewell.
