1 146 LIFE : OUTLINES OF GENERAL BIOLOGY 



What do these squares mean, e.g. mS, as moved-Space, or move- 

 ment-Space? Take a point, and move it, to generate a straight line; 

 next move this line, to generate a plane, and again move the plane 

 into a solid. Or, let us rotate an isosceles triangle into a vertical 

 cone ; and so on ; in brief, mS is the square for thinking out our pure 

 geometry. Next sM, spaced-Movement, is our space-measurement 

 of distances moved, be this of growth or march, of flight or 

 light. Now introducing Time, sT, spaced Time, is most familiarly 

 expressed by sundial, and watch or clock-face. Next tS, timed 

 Space, is space measured by time; as from an hour's march (the 

 old "league"), up to c for light-velocity, as limit; and thus to 

 "light-years" for stellar distances. What is mT, movement of 

 Time? Surely Past, Present, and Possible — and this with plus 

 or minus acceleration, in our perspectives of these. And tM, 

 timed Movement, is familiar to us in clock-pendulum, and clock- 

 or watch-hands, and again by stop- watch, and metronome on 

 the piano. 



All our nine squares are thus intelligible, and we submit more 

 clearly than in the mathematician's and physicist's customary use 

 of "space-time" as a single term, yet by which at one time they 

 seem to mean smT, at other times sT or Ts, or what not, if not 

 any or aU inter-relations? If so, is not the above attempt towards 

 clearing-up this idea a desirable one ? 



Let us try the same game in the physical level. First, with the 

 elder physicists of our younger days, let us assume Ether as filling 

 Space, and also put physical Energy in the square of Movement; 

 say then Et, En, and Ti. What can we now read of their inter- 

 relations ? 



Thus en-Et, energised Ether, aids us to image Faraday's "lines of 

 Force" around his magnet; and et-En, ethereal Energy, is familiar 

 to us in the undulatory conception of light, and even to its spec- 

 trum as well; so Clerk Maxwell's correlation of en-Et and et-En, 

 as of light and electro-magnetism, is more plainly rationalised for 

 us. So ti-Et, timed-Ether, helps us to image the velocity of light, 

 and even how this can be conceived to have its limit, c, in the 

 nature of ether. What is et-Ti, ethered or etherealised Time? And
