with improving conditions, until finally trees and animals, 

 and lastly man is made. By this there will be improved 

 conditions, such as the absence of a tail, improvement of 

 throat and tongue, articulate speech, and of the head 

 generally. These things do not appear in any of the 

 inferior animals. 



It requires two persons to make one bargain. It takes 

 two forces to give one resultant. This is seen in all the 

 previous examples, and it appears in no preceding philo- 

 sophies. Had our ancestors devoted their attention to this 

 fact, instead of giving the whole strength of their minds 

 to ancient languages and Aristotelic logic, we should have 

 been spared the pains of writing innate ideas. 



In this little tract (which shows my feeble health) I have 

 brought every thing from one single principle, that of 

 emanation or repulsion, which I have shown does not con- 

 tradict the other forces, but is in complete harmony with 

 them, to wit : motion, sound, heat, light, electricity, mag- 

 netism, and lastly, life itself, both vegetal and animal. 

 In all these, except the last, I have made man the first 

 mover, typified as a node which terminates at the nearest 

 circumference as a venter, which then takes course until 

 the centre, which of course is a node, whence the node 

 carries forth to the final circumference or venter. 



For the last case, the earth is the first node, and generates 

 life at its venter or circumference. Matter is not dead, but 

 emanates constantly, and generates life positive and nega- 

 tive, vegetal and animal, in the dark and moist bosom of 

 the earth, and shoves the result forth to the surface. The 

 vegetal and animal grow by feeding, and their existence 

 dies by exhaustion and wearing. 



I have drawn everything from heat, which the earth 

 always emanates, and will, we trust, be found sufficient to 

 furnish all the energy required. Those who live in glass 

 houses should not throw stones at the passengers.
