If we could travel into the past, it's mind-boggling what would be possible. For one thing, history would become an experimental science, which it certainly isn't today. The possible insights into our own past and nature and origins would be dazzling. For another, we would be facing the deep paradoxes of interfering with the scheme of causality that has led to our own time and ourselves. I have no idea whether it's possible, but it's certainly worth exploring.
Can't repeat the past?" he cried incredulously. "Why of course you can!" He looked around him wildly, as if the past were lurking here in the shadow of his house, just out of reach of his hand.
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.
Whenever our ethnic or national prejudices are aroused, in times of scarcity, during challenges to national self esteem or nerve, when we agonize about our diminished cosmic place and purpose, or when fanaticism is bubbling up around us - then, habits of thought familiar from ages past reach for the controls.
We human beings have enormous difficulty in focusing on the present; we always thinking about what we did, about how we could have done it better.... or else we think about the future, about what we're going to do.... But at this precise moment, you also realize that you can change your future by bringing the past into the present. Past and future only exist in our mind. The present moment, though, is outside of time, it's Eternity.... It isn't what you did in the past the will affect the present. It's what you do in the present that will redeem the past and thereby change the future.
Real spirituality is going through fire. Real spirituality is rebellion against all that is rotten, against all that is past, against all that is being forced on you by others, against all conditionings. Real spirituality is the greatest rebellion there is. It is risky, it is adventurous, it is dangerous. So beware of pseudo spirituality which is always there, available, easily available at the door.
I think that part of my optimism comes from the belief that we as a people could actually, regardless of all the disadvantage of the past, regardless of the fact that a lot of other folks got a head start in the race, if we were able to make the race fair right now.
It is time, therefore, to abandon the superstition that natural science cannot be regarded as logically respectable until philosophers have solved the problem of induction. The problem of induction is, roughly speaking, the problem of finding a way to prove that certain empirical generalizations which are derived from past experience will hold good also in the future.
You think you might know something about yourself or why you act or react in certain ways and then you come to new information and suddenly you see your past and your present in a completely different light.
There's nobody who would be willing to do an interview on a regular basis that you can't go and Google and find out what has happened to them in the past week. There's nobody.
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.
