The future is merely a shadow which blocks out the joys of the present and emphasizes the miseries of the past.

The past exists only in our memories, the future only in our plans. The present is our only reality. The tree that you are aware of intellectually, because of that small time lag, is always in the past and therefore is always unreal. Any intellectually conceived object is always in the past and therefore unreal. Reality is always the moment of vision before the intellectualization takes place. There is no other reality.

Some minds will jump here jump to the conclusion that a past idea cannot in any sense be present. But that is hasty and illogical. How extravagant too, to pronounce our whole knowledge of the past to be mere delusion! Yet it would seem that the past is completely beyond the bounds of possible experience as a Kantian thing-in-itself.

While I complain of being able to glimpse no more than the shadow of the past, I may be insensitive to reality as it is taking shape at this very moment, since I have not reached the stage of development at which I would be capable of perceiving it. A few hundred years hence, in this same place, another traveller, as despairing as myself, will mourn the disappearance of what I might have seen, but failed to see.

The past is an interpretation. The future is an illusion.
The world does not move through time as if it were a straight line, proceeding from the past to the future.
Instead, time moves through and within us, in endless spirals. Eternity does not mean infinite time, but simply timelessness.

The illusion that we understand the past fosters overconfidence in our ability to predict the future.

We must look upon what is to occur as having already occurred, and see nothing but the present in the future, for the future is but the present a little farther on.

The past gives you an identity and the future holds the promise of salvation. … Both are illusions.

Mistaking a naive observation of the past as something definitive or representative of the future is the one and only cause of our inability to understand the Black Swan.

What lies ahead seems unlikely; when it becomes the past, it seems inevitable.

Reality is a question of perspective; the further you get from the past, the more concrete and plausible it seems - but as you approach the present, it inevitably seems more and more incredible. Suppose yourself in a large cinema, sitting at first in the back row, and gradually moving up, row by row, until your nose is almost pressed against the screen. Gradually the stars' faces dissolve into dancing grain; tiny details assume grotesque proportions; the illusion dissolves - or rather, it becomes clear that the illusion itself is reality.

And so it is with our own past. It is a labour in vain to attempt to recapture it: all the efforts of our intellect must prove futile. The past is hidden somewhere outside the realm, beyond the reach of intellect, in some material object (in the sensation which that material object will give us) of which we have no inkling. And it depends on chance whether or not we come upon this object before we ourselves must die.
