There is one bit of advice given us by the ancient Greeks, and by the Jews in the Old Testament, and by the great Christian teachers of the Middle Ages, which the modern economic system has completely disobeyed. All these people told us not to lend money at interest; and lending money at interest - what we call investment - is the basis of our whole system.
C. S. LewisGood, as it ripens, becomes continually more different not only from evil but from other good.
C. S. LewisThe way for a person to develop a style is (a) to know exactly what he wants to say, and (b) to be sure he is saying exactly that.
C. S. LewisBoth good and evil, when they are full grown, become retrospective...That is what mortals misunderstand. They say of some temporary suffering, 'No future bliss can make up for it,' not knowing that Heaven, once attained, will work backwards and turn even that agony into a glory. And of some sinful pleasure they say 'Let me but have this and I'll take the consequences': little dreaming how damnation will spread back and back into their past and contaminate the pleasure of the sin.
