Everything that makes diversity of kinds, of species, differences, properties everything that consists in generation, decay, alteration and change is not an entity, but a condition and circumstance of entity and being, which is one, infinite, immobile, subject, matter, life, death, truth, lies, good and evil.
Giordano Bruno
He who rejects change is the architect of decay. The only human institution which rejects progress is the cemetery.
Harold Wilson
Moral and spiritual decay have brought about the demise of more great nations (empires) than any invading enemy force, plague, famine and nature disasters combined
Joseph P. Martino
Of all our planet's activities--geological movements, the reproduction and decay of biota, and even the disruptive propensities of certain species (elephants and humans come to mind)--no force is greater than the hydrologic cycle.
RICHARD BANGS
Without adventure civilization is in full decay
Alfred North Whitehead
When private virtue is hazarded on the perilous cast of expediency, the pillars of the republic, however apparent their stability, are infected with decay at the very centre.
Edwin Hubbell Chapin
Fascism is capitalism in decay
Vladimir Lenin
One of the most devastating experiences in human life is disillusionment. Of course there are some illusions the disillusionment of which is healthy. It takes two things to bowl over a tree a heavy wind outside and decay inside. Much of the moral wreckage is caused by inner cynicism a disgust with life's futility, an inability to see sense in it. A person in that mood is an easy mark for the next high wind.
Art Sisson
Time on its back bears all things far away - Full many a challenge is wrought by many a day - Shape, fortune, name, and nature all decay
Plato
Tradition becomes our security, and when the mind is secure it is in decay
Jiddu Krishnamurti
You making haste on decay: not blameworthy; life is good, be it stubbornly long or suddenly A mortal splendor: meteors are not needed less than mountains: shine, perishing republic.
Robinson Jeffers
The goal of every culture is to decay through over-civilization; the factors of decadence, -- luxury, skepticism, weariness and superstition, -- are constant. The civilization of one epoch becomes the manure of the next.
Cyril Connolly
Trade's proud empire hastes to swift decay.
Samuel Johnson
Science, like life, feeds on its own decay. New facts burst old rules; then newly divined conceptions bind old and new together into a reconciling law.
William James
A comfortable old age is the reward of a well-spent youth. Instead of its bringing sad and melancholy prospects of decay, it would give us hopes of eternal youth in a better world.
Maurice Chevalier
