 out of which anything can be made by the creature 

 which wants to make it. Everything depends upon 

 whether a creature knows its own mind sufficiently 

 well, and has enough faith in its own powers of 

 achievement. When these two requisites are wanting, 

 the strongest giant cannot lift a two-ounce weight;

 another ; and then, when it has met with a nutritive 

 particle, extemporises a stomach for its reception, by 

 wrapping its soft body around it. Another, instead 

 of going about in search of food, remains in one place, 

 but projects its protoplasmic substance into long
