If you learn one thing from having lived through decades of changing views, it is that all predictions are necessarily false.
M. H. Abrams
The job of theorists, especially in biology, is to suggest new experiments. A good theory makes not only predictions, but surprising predictions that then turn out to be true. (If its predictions appear obvious to experimentalists, why would they need a theory?)
Francis Crick
The child must be brought up free (that he allow others to be free). He must learn to endure the restraint to which freedom subjects itself for its own preservation (experience no subordination to his command). Thus he must be disciplined. This precedes instruction. Training must continue without interruption. He must learn to do without things and to be cheerful about it. He must not be obliged to dissimulate, he must acquire immediate horror of lies, must learn so to respect the rights of men that they become an insurmountable wall for him. His instruction must be more negative. He must not learn religion before he knows morality. He must be refined, but not spoiled (pampered). He must learn to speak frankly, and must assume no false shame. Before adolescence he must not learn fine manners ; thoroughness is the chief thing. Thus he is crude longer, but earlier useful and capable.
Immanuel Kant
Already I had learned from thee that because a thing is eloquently expressed it should not be taken to be as necessarily true; nor because it is uttered with stammering lips should it be supposed false. Nor, again, is it necessarily true because rudely uttered, nor untrue because the language is brilliant. Wisdom and folly both are like meats that are wholesome and unwholesome, and courtly or simple words are like town-made or rustic vessels — both kinds of food may be served in either kind of dish.
Augustine of Hippo
In the heart of the sphere of everything that keeps changing, there one thing that never changes—life. Life is the one thing that stays with me until the very end. Today, people may like me. Tomorrow, they may not. But my life is still there. It is not subject to good and bad. Human beings are the thinkers—homo sapiens—the ones with the brains. We can think about things, and in our thoughts, everything keeps changing. In our moods, everything keeps changing. Yet, in our beings, there is the heart, and the heart does not change because it is consistent with only one thing. Our needs on the outside change all the time, but the heart's need never changes. It is consistently the same, and always will be.
Maharaji (Prem Rawat)
The science of political economy is essentially practical, and applicable to the common business of human life. There are few branches of human knowledge where false views may do more harm, or just views more good.
