As for myself, I confess to a preference for clear-cut situations, for radical and even extreme positions. But I also feel a secret and very strong attraction to ambiguous situations.. ..for example, that hovering moment when it is no longer day and not yet night, the shades of emotion between indifference and friendship … (they) are so fascinating because they are so indefinable. That which is pure transition, is all the more appealing to the mind because of its elusiveness.
The aesthetic event is something as evident, as immediate, as indefinable as love, the taste of fruit, of water. We feel poetry as we feel the closeness of a woman, or as we feel a mountain or a bay. If we feel it immediately, why dilute it with other words, which no doubt will be weaker than our feelings?jorge luis borges
I fear, the inevitable conclusion we must all come to is, that in the world happiness is quite indefinable. We can no more grasp it than we can grasp the sun in the sky or the moon in the water. We can feel it interpenetrating our whole being with warmth and strength; we can see it in a pale reflection shining elsewhere; or in its total absence, we, walking in darkness, learn to appreciate what it is by what it is not.dinah maria mulock
Language, he understood, was chiefly important for the beauty of its sounds, by its possession of words resonant, glorious to the ear, by its capacity, when- exquisitely arranged, of suggesting wonderful and indefinable impressions, perhaps more ravishing and farther removed from the domain of strict thought than the impressions excited by music itself.arthur machen
