The stone that was rolled before Christ's tomb might appropriately be called the philosopher's stone because its removal gave not only the pharisees but, now for 1800 years, the philosophers so much to think about.
Soren KierkegaardMaturity consists in the discovery that there comes a critical moment where everything is reversed, after which the point becomes to understand more and more that there is something which cannot be understood.
Soren Kierkegaard...the reason for [this age's] anxiety and unrest is because in one direction, 'truth' increases in scope and quantity - via science and technology - while in the other, certainty and confidence steadily decline. Our age is a master in developing truths while being wholly indifferent to certitude. It lacks confidence in the good.
