„Letters are signs of things, symbols of words, whose power is so great that without a voice they speak to us the words of the absent; for they introduce words by the eye, not by the ear.“

„There are words agreeable to the eye (in the same way there are words agreeable to the ear). By a fortunate combination of the letters that form them or by the harmony of these letters. For each letter has its shape.“

—  Joseph Joubert French moralist and essayist 1754 - 1824

The word within a word, unable to speak a word,
Swaddled with darkness.“

—  Richard M. Weaver American scholar 1910 - 1963

„Hear the voice of the Bard,
Who present, past, and future, sees;
Whose ears have heard
The Holy Word
That walked among the ancient trees.“

„Be Impeccable with Your Word. Speak with integrity. Say only what you mean. Avoid using the word to speak against yourself or to gossip about others. Use the power of your word in the direction of truth and love.“

—  Miguel Ángel Ruiz, libro Los cuatro acuerdos

„Words are life. Words are light. Words are power. Words are energy. Words are truth. Words can enliven and words can also kill. Words can give hope, or plunge us into despair. People use words to build peace, and use words to make war. Words can create walls between cultures, religions, and nations. And words can also build bridges. The existence of an individual, a family, a community, a country, and our planet is being led to good or to evil through the power of the words we speak. The words we speak are responsible for everything that happens in this world. We, therefore, must be responsible for the words we speak. On behalf of future generations, I hope that each of us will do all we can to speak only bright, light-filled words, so that one day, our descendants will be born into a world filled with light. There is no time to lose. Starting at this very moment, I hope all of us will take a close look at the words we have been using and make constant efforts to fill them with brightness.“

—  Alexis Karpouzos 1967

„Every phenomenon of nature was a word, — the sign, symbol and pledge of a new, mysterious, inexpressible but all the more intimate union, participation and community of divine energies and ideas.

—  Johann Georg Hamann German philosopher 1730 - 1788

„There is a deep power in words that speak the truth“

—  P. C. Cast, libro Tempted

„There's a light in a woman's eyes that speaks louder than words.“

„We can speak without voice to the trees and the clouds and the waves of the sea. Without words they respond through the rustling of leaves and the moving of clouds and the murmuring of the sea.“

—  Paul Tillich German-American theologian and philosopher 1886 - 1965

„Speaking much also is a sign of vanity; for he that is lavish in words is a niggard in deeds.“

—  Walter Raleigh English aristocrat, writer, poet, soldier, courtier, spy, and explorer 1554 - 1618

„[A]ll our symbols have the same purpose; words are merely the symbols we use most commonly. The function of words in human thought is to stand for things which are not present to the senses, and allow the mind to manipulate them—things, concepts, ideas, everything that does not have a physical reality in front of us now.“

—  Jacob Bronowski Polish-born British mathematician 1908 - 1974

„It got so that when he closed his eyes, letters and words danced in his mind. He thought of little else during that time.“
