Context

“Why should we be more ashamed to weep than to laugh before company? We may often have as real occasion to do the one as to do the other: but we always feel that the spectators are more likely to go along with us in the agreeable, than in the painful emotion. It is always miserable to complain, even when we are oppressed by the most dreadful calamities. But the triumph of victory is not always ungraceful. Prudence, indeed, would often advise us to bear our prosperity with more moderation; because prudence would teach us to avoid that envy which this very triumph is, more than any thing, apt to excite.” source
