If you want the exact moment in time, it was conceived mentally on 8th March in this year one thousand six hundred and eighteen, but submitted to calculation in an unlucky way, and therefore rejected as false, and finally returning on the 15th of May and adopting a new line of attack, stormed the darkness of my mind. So strong was the support from the combination of my labour of seventeen years on the observations of Brahe and the present study, which conspired together, that at first I believed I was dreaming, and assuming my conclusion among my basic premises. But it is absolutely certain and exact that "the proportion between the periodic times of any two planets is precisely the sesquialterate proportion of their mean distances..."

I'd had enough. I felt so low: I was 26 and there was an exact moment when I just knew I didn't want to do it any more. I was out with two very good friends of mine, who are now dead. They both died of alcoholism. It was about 3am and I thought: "I don't want this. I have to stop." I'd felt that before, a hundred times, but I woke up next morning and I still didn't want to do it. And that was the first time in ten years I'd had that strength of feeling.

Men are qualified for civil liberty in exact proportion to their disposition to put moral chains upon their own appetites, — in proportion as their love to justice is above their rapacity, — in proportion as their soundness and sobriety of understanding is above their vanity and presumption, — in proportion as they are more disposed to listen to the counsels of the wise and good, in preference to the flattery of knaves. Society cannot exist, unless a controlling power upon will and appetite be placed somewhere; and the less of it there is within, the more there must be without. It is ordained in the eternal constitution of things, that men of intemperate minds cannot be free. Their passions forge their fetters.

 

Edmund Burke

 

I say this in order to impress upon you, if you are not already so impressed, that no small matter should divert us from our great purpose. There may be some irregularities in the practical application of our system. It is fair that each man shall pay taxes in exact proportion to the value of his property; but if we should wait before collecting a tax to adjust the taxes upon each man in exact proportion with every other man, we should never collect any tax at all. There may be mistakes made sometimes; things may be done wrong while the officers of the Government do all they can to prevent mistakes. But I beg of you, as citizens of this great Republic, not to let your minds to carried off from the great work we have before us. This struggle is too large for you to be diverted from it by any small matter.

 

Abraham Lincoln

 

The first thing necessary for a constructive dealing with time is to learn to live in the reality of the present moment. For psychologically speaking, this present moment is all we have. The past and future have meaning because they are part of the present: a past event has existence now because you are thinking of it at this present moment, or because it influences you so that you, as a living being in the present, are that much different. The future has reality because one can bring it into his mind in the present. Past was the present at one time, and the future will be the present at some coming moment. To try to live in the "when" of the future or the "then" of the past always involves an artificiality, a separating one's self from reality; for in actuality one exists in the present. The past has meaning as it lights up the present, and the future as it makes the present richer and more profound.

The only other instance of judicial iniquity, the mention of which, after the condemnation of Socrates, would not be an anti-climax: the event which took place on Calvary rather more than eighteen hundred years ago. The man who left on the memory of those who witnessed his life and conversation, such an impression of his moral grandeur, that eighteen subsequent centuries have done homage to him as the Almighty in person, was ignominiously put to death, as what? As a blasphemer. Men did not merely mistake their benefactor; they mistook him for the exact contrary of what he was, and treated him as that prodigy of impiety, which they themselves are now held to be, for their treatment of him.
