Some forms of Kantianism put great weight on “what we can imagine” holding that this can be a source of insight into necessary connections. Thus various of Kant’s arguments about space and time depend on the purported fact that it is impossible for us to imagine certain things: we can know, Kant claims, a priori that space has only three dimensions because we cannot imagine it as having more than three dimensions. History in the form of non-Euclidean geometry and modern physics has put paid to that particular line of argument, but in general we should beware of depending too much on “What we can imagine?,” especially in politics. As Nietzsche puts it somewhere, sometimes the fact that you can’t imagine a situation in which things are very different from the way they are now is not an especially good argument for the claim that they must be as they now are, but, rather, represents a failure of your powers about which you should feel mildly apologetic.

Imagine what would happen if the nations of the world spent as much on development as on building the machines of war. Imagine a world where every human being would live in freedom and dignity. Imagine a world in which we would shed the same tears when a child dies in Darfur or Vancouver. Imagine a world where we would settle our differences through diplomacy and dialogue and not through bombs or bullets. Imagine if the only nuclear weapons remaining were the relics in our museums. Imagine the legacy we could leave to our children.
Imagine that such a world is within our grasp.Mohamed ElBaradei
Imagine discovering a continent so vast that it may have no end to its dimensions. Imagine a new world with more resources than all our future greed might exhaust, more opportunities than there will ever be entrepreneurs enough to exploit, and a peculiar kind of real estate that expands with development. Imagine a place where trespassers leave no footprints, where goods can be stolen infinite number of times and yet remain in the possession of their original owners, where business you never heard of can own the history of your personal affairs...
John Perry Barlow
Some philosophers have believed that a philosophical clarification of space also provided a solution of the problem of time. Kant presented space and time as analogous forms of visualization and treated them in a common chapter in his major epistemological work. Time therefore seems to be much less problematic since it has none of the difficulties resulting from multidimensionality. Time does not have the problem of mirror-image congruence, i.e., the problem of equal and similarly shaped figures that cannot be superimposed, a problem that has played some role in Kant's philosophy. Furthermore, time has no problem analogous to non-Euclidean geometry. In a one-dimensional schema it is impossible to distinguish between straightness and curvature. ...A line may have external curvature but never an internal one, since this possibility exists only for a two-dimensional or higher continuum. Thus time lacks, because of its one-dimensionality, all those problems which have led to philosophical analysis of the problems of space.
Hans Reichenbach
I think we're at a time in American history that's probably analogous to, maybe, Rome before the first emperors, when the Republic started to fall... I think if you look at the pattern of events, if you look at the disputed election of 2000, can you imagine? In America, people are trying to recount ballots and a partisan mob is pounding on the glass and threatening the counters? Can you imagine that? Can you imagine a political party which does its best to keep any representatives from another party — who've even been affiliated with another party — from getting a business job in the nation's capital? Can you imagine a political party that wants to redistrict so that its opponents can be driven out entirely?...it's a different time in America and the Republic is — this election is about a lot more than jobs. I'm not sure everybody in America sees it right now. But I see it, I feel it.

Reader! Imagine a school-boy who has outgrown his clothes. Imagine the repairs made on the vestments where the enlarged frame had burst the narrow limits of its inclosure. Imagine the additions made where the projecting limbs had fairly and far emerged beyond the confines of the garment. Imagine the boy still growing, and the clothes, mended all over, now more than ever in want of mending — such is chemistry, and such its nomenclature.
