in the fire, ѓif Time is really only a fourth dimension of Space, why is it, and why has it always been, regarded as something different? And why cannot we move in Time as we move about in the other dimensions of Space?Ш

The Time Traveller smiled.ѓAre you sure we can move freely in Space? Right and left we can go, backward and forward freely enough, and men always have done so. I admit we move freely in two dimensions. But how about up and down? Gravitation limits us there.Ш

ѓNot exactly,Ш said the Medical Man. ѓThere are balloons.Ш

ѓBut before the balloons, save for spasmodic jumping and the inequalities of the surface, man had no freedom of vertical movement.Ш ѓStill they could move a little up and down,Ш said the Medical Man.

ѓEasier, far easier down than up.Ш

ѓAnd you cannot move at all in Time, you cannot get away from the present moment.Ш

ѓMy dear sir, that is just where you are wrong. That is just where the whole world has gone wrong. We are always getting away from the present movement. Our mental existences, which are immaterial and have no dimensions, are passing along the Time-Dimension with a uniform velocity from the cradleto the grave. Just as we should travel DOWN if we began our existence fifty miles above the earthЈs surface.Ш

ѓBut the great difficulty is this,Ш interrupted the Psychologist. ѓYou CAN move about in all directions of Space, but you cannot move about in Time.Ш

ѓThat is the germ of my great discovery. But you are wrong to say that we cannot move about in Time. For instance, if I am recalling an incident very vividly I go back to the instant of its occurrence: I become absent-minded, as you say. I jump back for a moment. Of course we have no means of staying back for any length of Time, any more than a savage
