156 WHAT IS LIFE 



3. Life consists of the same constituent units as does 

 matter. 



4. Life represents a manner of combination of 

 ultimate units different from the pattern of their com- 

 bination to form the chemical atoms, or matter. 



5. In the living organism, life is an intraatomic 

 quantity. 



6. This definition of life applies to all life-forms 

 without exception: That which sometimes has been 

 described vaguely as "the life-principle," that which 

 determines the living state (or the state of living) 

 whether of plants (all plants) or of animals (the entire 

 animal kingdom) or of man, alike in all, is the 

 intraatomic quantity "life." 



7. Life forms a definite series, different from the 

 series that from atomic number 1 to atomic number 

 92, is matter. All life-forms are alike basically in 

 that, or in so far as, life is owing to a peculiar manner 

 of the combination of ultimate units. The differences 

 between one form and an other form are determined 

 quantitatively; but there is no arithmetical progression 

 (as in the elements), a very large number of dif- 

 ferent forms and variations of forms being possible. 



8. Specific and different properties necessarily 

 characterize the combination of ultimate units after 

 a pattern unlike that of the chemical atoms, or 

 matter; the peculiar manner of combination that
