I established the rule that once we hire an employee, his school records are a matter of the past and are no longer used to evaluate his work or decide on his promotion.
The past,' he thought, 'is linked with the present by an unbroken chain of events flowing one out of another.' And it seemed to him that he had just seen both ends of that chain; that when he touched one end the other quivered.
We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves. If what we are now has been the result of our own past actions, it certainly follows that whatever we wish to be in the future can be produced by our present actions; so we have to know how to act.
This is a world that is much more uncertain than the past. In the past we were certain, we were certain it was us versus the Russians in the past. We were certain, and therefore we had huge nuclear arsenals aimed at each other to keep the peace. That's what we were certain of... You see, even though it's an uncertain world, we're certain of some things. We're certain that even though the "evil empire" may have passed, evil still remains.
There are two processes which we adopt consciously or unconsciously when we try to prophesy. We can seek a period in the past whose conditions resemble as closely as possible those of our day, and presume that the sequel to that period will, save for some minor alterations, be similar. Secondly, we can survey the general course of development in our immediate past, and endeavor to prolong it into the near future. The first is the method the historian; the second that of the scientist. Only the second is open to us now, and this only in a partial sphere.
Through the ghoul-guarded gateways of slumber, Past the wan-mooned abysses of night, I have lived o'er my lives without number, I have sounded all things with my sight.
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
The Chinese government wants me to say that for many centuries Tibet has been part of China. Even if I make that statement, many people would just laugh. And my statement will not change past history. History is history.
