“Angels can fly because they can take themselves lightly.”
Chesterton uses levity as a metaphor against swollen self-importance: the ability to take oneself less heavily becomes part of spiritual freedom rather than evidence that serious responsibilities do not matter.
Source note: Orthodoxy, Chapter VII, “The Eternal Revolution,” Project Gutenberg #130. The sentence belongs to Chesterton’s explicitly Christian contrast between levity and pride; he immediately describes pride as a downward heaviness and self-forgetfulness as something one rises toward.

“A thing of beauty is a joy for ever.”
Keats opens the poem by claiming that beauty can continue to give delight beyond the instant in which it is first encountered.
Source note: Endymion, Book I, opening line; Project Gutenberg #24280. This is a poetic proposition within a Romantic work, not an empirical rule that every aesthetic experience remains pleasurable forever.

Source note: The Twilight of the Idols, “Maxims and Missiles,” maxim 33, Anthony M. Ludovici translation, Project Gutenberg #52263. The maxim begins comically with the sound of a bagpipe before arriving at this sentence.

“The most manifest sign of wisdom is a continual cheerfulness.”
Montaigne associates wisdom with a settled, clear disposition rather than with performative gloom or intellectual severity.
Source note: Essays of Montaigne, Book I, Charles Cotton translation; the surrounding passage contrasts wisdom with joyless scholastic display.

“Therefore the sufficiency of contentment is an enduring and unchanging sufficiency.”
Contentment supplies a form of enoughness that does not depend on continually acquiring more, making inward sufficiency less vulnerable to comparison and appetite.
Source note: Tao Teh King, chapter 46, James Legge translation; the statement follows warnings about ambition, discontent, and the wish to keep getting.
