PROGRESS, BIOLOGICAL AND 

 OTHER 



* Usus et impigrae simul experientia mentis 

 Paulatim docuit pedetemtim progredientes.' 



— Lucretius. 



*A8 natural selection works solely by and for the good of each 

 being, all corporeal and mental environments will tend to progress 

 towards perfection.' — Charles Darwin. 



* Social progress means the checking of the cosmic process at 

 every step and the substitution for it of another which may be 

 called the ethical process.' — T. H. Huxley. 



* It is probable that what hindered Kant from broaching his 

 theory of progress with as much confidence as Condorcet was 

 his perception that nothing could be decisively affirmed about the 

 causes of civilization until the laws of its movement had been 

 discovered. He saw that this was a matter for future scientific 

 investigation.' — J. B. Bury.
