Passion makes a person stop eating, sleeping, working, feeling at peace. A lot of people are frightened because, when it appears, it demolishes all the old things it finds in its path.
Curiosity, which may or may not eventuate in something useful, is probably the most outstanding characteristic of modern thinking ... Institutions of learning should be devoted to the cultivation of curiosity, and the less they are deflected by the consideration of immediacy of application, the more likely they are to contribute not only to human welfare, but to the equally important satisfaction of intellectual interest, which may indeed be said to have become the ruling passion of intellectual life in modern times.
Passions are no more forgiving than human laws and they reason more justly. Are they not based on a conscience of their own, infallible as an instinct?
The true lover of knowledge naturally strives for truth, and is not content with common opinion, but soars with undimmed and unwearied passion till he grasps the essential nature of things.
But we never get back our youth… The pulse of joy that beats in us at twenty becomes sluggish. Our limbs fail, our senses rot. We degenerate into hideous puppets, haunted by the memory of the passions of which we were too much afraid, and the exquisite temptations that we had not the courage to yield to.
Friends now fast sworn,
Whose double bosoms seems to wear one heart,
Whose hours, whose bed, whose meal and exercise
Are still together, who twin, as 'twere, in love,
Unseparable, shall within this hour,
On a dissension of a doit, break out
To bitterest enmity; so fellest foes,
Whose passions and whose plots have broke their sleep
To take the one the other, by some chance,
Some trick not worth an egg, shall grow dear friends
And interjoin their issues.
To be free of all authority, of your own and that of another, is to die to everything of yesterday, so that your mind is always fresh, always young, innocent, full of vigour and passion. It is only in that state that one learns and observes. And for this, a great deal of awareness is required, actual awareness of what is going on inside yourself, without correcting it or telling it what it should or should not be, because the moment you correct it you have established another authority, a censor.
