i6 THEORETICAL BIOLOGY 



organisation of our subject, which else hes shrouded in utter 

 darkness. Whatever the perception, the activity is of the 

 same kind ; different quahties are constantly being associated 

 into unities. The power of the subject that exercises this 

 apperceptive activity is for ever creating new structures ; in 

 its very nature, it is a formative force. 



The material for this construction is furnished by the 

 qualities ; the laws governing the construction are the forms. 

 From force, material and law the organisation of our subject 

 becomes revealed to us. 



Hence we are justified in calling space a law, since it is 

 the most general form of sense-perception ; and since the 

 activity of our mind is the only part of Nature directly known 

 to us, its laws are the only ones that we can justifiably call 

 laws of Nature. The determination which space imposes on 

 all objects is undoubtedly a law of Nature. 



This determination according to law, imposed by space 

 on all objects, is, as we have seen, twofold : — (i) possibility of 

 movement and (2) position with regard to the three planes 

 of direction. From this consideration arises the question 

 whether space, although it represents a fundamental law for 

 all objects, may not itself be merely a creation by apperception. 



THE ORGAN THAT GIVES DIRECTION IN SPACE 



The clue put into our hands by Kant to enable us to pene- 

 trate the myster}^ of the organisation of our subject, depends 

 on a conclusion drawn from the activity of the subject itself as 

 to its own constitution, and hence leaves unsolved many ques- 

 tions as to the nature of that organisation. In contrast to this, 

 the organisation of our body lies exposed before our eyes, 

 and does not have to be revealed by conclusions drawn from 

 its activity.
