Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
It is my conviction that pure mathematical construction enables us to discover the concepts and the laws connecting them, which gives us the key to the understanding of nature ... In a certain sense, therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.
Reality has no security and that is its beauty. Life has no security and that is its beauty. Because there is no security, there is adventure. Because the future is unknown, nobody knows what is going to happen the next moment. That's why there is challenge, growth, adventure. If you miss adventure, you miss all. If your life is not that of an adventure, of a search into the unknown, then you are living in vain.
Thus the man who is responsive to artistic stimuli reacts to the reality of dreams as does the philosopher to the reality of existence; he observes closely, and he enjoys his observation: for it is out of these images that he interprets life, out of these processes that he trains himself for life.
An Irishman's imagination never lets him alone, never convinces him, never satisfies him; but it makes him that he can't face reality nor deal with it nor handle it nor conquer it: he can only sneer at them that do, and be 'agreeable to strangers', like a good-for-nothing woman on the streets.
The past is no more and the future is not yet. The only right person is one who lives moment to moment, whose arrow is directed to the moment, who is always here and now; wherever he is, his whole consciousness, his whole being, is involved in the reality of here and in the reality of now.
The aim of the poet is to inform or delight, or to combine together, in what he says, both pleasure and applicability to life. In instructing, be brief in what you say in order that your readers may grasp it quickly and retain it faithfully. Superfluous words simply spill out when the mind is already full. Fiction invented in order to please should remain close to reality.
In the search for reality, energy creates its own discipline. But mere discipline, without full comprehension of all this, has no meaning, it is a most destructive thing.
