At present, man applies to nature but half his force. He works on the world with his understanding alone. He lives in it, and masters it by a penny-wisdom; and he that works most in it, is but a half-man, and whilst his arms are strong and his digestion good, his mind is imbruted, and he is a selfish savage. His relation to nature, his power over it, is through the understanding; as by manure

Context

“He perceives that if his law is still paramount, if still he have elemental power, if his word is sterling yet in nature, it is not conscious power, it is not inferior but superior to his will. It is Instinct.' Thus my Orphic poet sang. At present, man applies to nature but half his force. He works on the world with his understanding alone. He lives in it, and masters it by a penny-wisdom; and he that works most in it, is but a half-man, and whilst his arms are strong and his digestion good, his mind is imbruted, and he is a selfish savage. His relation to nature, his power over it, is through the understanding; as by manure; the economic use of fire, wind, water, and the mariner's needle; steam, coal, chemical agriculture; the repairs of the human body by the dentist and the surgeon. ​This is such a resumption of power, as if a banished king should buy his territories inch by inch, instead of vaulting at once into his throne.” source
