A mature person is one who does not think only in absolutes, who is able to be objective even when deeply stirred emotionally,who has learned that there is both good and bad in all people and in all things, and who walks humbly and deals charitably with the circumstances of life, knowing that in this world no one is all-knowing and therefore all of us need both love and charity.
Eleanor Roosevelt
We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.
Marie Curie
We need to be careful not to harbour any resentment against those who harm us, but rather to pray for them with love. Whatever any of our fellow men does, we should never think evil of him. We need always to have thoughts of love and always to think good of others. Look at Saint Stephen the first martyr. He prayed, Lord, do not hold this sin against them. We need to do the same.
Porphyrios of Kafsokalyvia
Art, and, above all, music, has a fundamental function, which is to catalyze the sublimation that it can bring about through all means of expression. It must aim through fixations which are landmarks, to draw [one] towards a total exaltation in which the individual mingles, losing his consciousness in a truth immediate, rare, enormous, and perfect. If a work of art succeeds in this undertaking even for a single moment, it attains its goal.
Iannis Xenakis
This increase in the life span and in the number of our senior citizens presents this Nation with increased opportunities: the opportunity to draw upon their skill and sagacityand the opportunity to provide the respect and recognition they have earned. It is not enough for a great nation merely to have added new years to lifeour objective must also be to add new life to those years.
