"The investigation of nature teaches us to recognise the omnipotence, the 

 perfection, and the inscrutable wisdom of an infinitely higher Being, in his works 

 and actions. So long as we are ignorant of these things, the perfect development 

 of the human mind cannot be hoped for, or even conceived. Without this know- 

 ledge the immortal spirit of man cannot attain to a consciousness of its own 

 dignity, or of the rank which it occupies in creation." LIEBIG'S Familiar Letters 

 on Chemistry.
