§ 18. Since the organisms composing the society have by our 
first axiom certain time-relations, since by our third axiom they 
seize upon the matter and energy of nature, a new idea comes in, 
that of their occupations. In a complex society like the human, 
more time-relations or occupations are to be observed than those 
which concern the direct utilisation of nature. By the aid of 
these considerations and of the preceding tables, the occupations 
arrange themselves as follows : — 
I. Operations on matter and energy, i.e ., concerned in 
1. Exploitation. 
2. Manufacture. 
3. Movement. 
(a) Transport. 
( b ) Trade. 
II. Operations on organisms composing given society. 
1. Service of non-cerebral functions. 
(a) Menial, domestic. 
2. Service of cerebral functions. 
(a) ^Esthetic, intellectual, moral. 
3. Service of co-ordination.
