"No." 



1 'Well, then! Besides, imagine this. All is the 

 same around the terrestrial globe; properly speak- 

 ing, there is no up or down, no right or left. We 

 call up the direction toward adjacent space, or to- 

 ward the sky ; but remember that there is sky also on 

 the other side of the earth, that there it is just the 

 same as we see it here, and that this is true for all 

 parts of the earth's surface. If it seemed to you 

 quite simple that the earth does not rush toward the 

 sky which is above us, why should you expect it to 

 rush toward the opposite sky? To fall toward the 

 opposite sky would be to rise, as the lark rises here, 

 when with one stroke of the wing it takes its flight 

 and soars above us."
