The uncertainty of events disturbs the purest enjoyments. [ De Levis ]

Extreme views are never just; something always turns up which disturbs the calculations formed upon their data. [ Beaconsfield ]

Contrast increases the splendour of beauty, but it disturbs its influence; it adds to its attractiveness, but diminishes its power. [ John Ruskin ]

Gaze not on beauty too much, lest it blast thee; nor too long, lest it blind thee; nor too near, lest it burn thee. If thou like it, it deceives thee; if thou love it, it disturbs thee; if thou hunt after it, it destroys thee. If virtue accompany it, it is the heart's paradise; if vice associate it, it is the soul's purgatory. It is the wise man's bonfire, and the fool's furnace. [ Quarles ]
