Enlightenment is man's leaving his self-caused immaturity. Immaturity is the incapacity to use one's intelligence without the guidance of another. Such immaturity is self-caused if it is not caused by lack of intelligence, but by lack of determination and courage to use one's intelligence without being guided by another. Sapere Aude! Have the courage to use your own intelligence! is therefore the motto of the enlightenment.
The craft with which the world is made runs also into the mind and character of men. No man is quite sane; each has a vein of folly in his composition, a slight determination of blood to the head, to make sure of holding him hard to some one point which Nature has taken to heart.
Poetry is not like reasoning, a power to be exerted according to the determination of the will. A man cannot say, 'I will compose poetry.' The greatest poet even cannot say it; for the mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness...and the conscious portions of our natures are unprophetic either of its approach or its departure.
I have been very fortunate in worldly matters; many men have worked much harder, and not succeeded half so well; but I never could have done what I have done, without the habits of punctuality, order, and diligence, without the determination to concentrate myself on one object at a time, no matter how quickly its successor should come upon its heels, which I then formed.
We must have a pure, honest, and warm-hearted motivation, and on top of that, determination, optimism, hope, and the ability not to be discouraged. The whole of humanity depends on this motivation.
The determination of the average man is not merely a matter of speculative curiosity; it may be of the most important service to the science of man and the social system. It ought necessarily to precede every other inquiry into social physics, since it is, as it were, the basis. The average man, indeed, is in a nation what the centre of gravity is in a body; it is by having that central point in view that we arrive at the apprehension of all the phenomena of equilibrium and motion.
It's very important that the determination of the US Congress to do what is is needed be made evident this week and by the actions of most of the members. I mean, you're not going to get total assent.
Most REAL change is slow. Happiness and joy are the purpose of life. If we know that the future will be very dark or painful, then we lose our determination to live. Therefore, life is something based on hope.
