1885.] The Relations of Mind and Matter. 1075 
bination of energies is a process which has its analogue in the outer 
world. Similar combinations take place in objects, and the ener- 
gies received from without combine with those within to produce: 
new conditions. If the mind has a substantial basis it must con- 
form, in every respect, to the principles which display themselves 
in external compounds of substance. Yet in this respect the 
mind seems to be -peculiarly active. The objects of the outer 
world consist of a dense aggregate of matter affected by a limited 
volume of energy. As all change is due to the interaction of 
this energy, external objects vary but slowly and slightly, slug- 
gishly resisting its action. In the case of the mind we may con- 
ceive its substance to be reduced to a minimum and its energy 
enhanced to a maximum. Thus its mobility is extreme, its sen- 
Sitiveness excessive, its interactions of energy rapid and incessant. . 
Its powers of change and of new formation of conditions are vast 
as compared with those of physical objects. 
And the molding of the mind of man by nature is but slightly 
due to its direct sensations from external objects. It is:very’ 
largely produced through the medium of other minds, since a 
leverage exists between mind and mind as between mind and 
Matter in producing conformity of conditions. In this indirect 
way a single mind may have been brought into conformity with 
` outer nature through the intermediate influence of millions of 
other minds, exercised through the preservation of their ideas in 
books, or through their effects‘upon human society. 
' We may close here with a brief consideration of the status of 
the human mind if its development could be continued to infinity. 
In such a case it would necessarily become an infinitely complete 
reproduction or representation of the universe, and infinitely sen- 
sitive and mobile to any modifications taking place in the vast 
domain of space. In the second place, it would be infinitely 
capable of producing within itself new combinations of energy.” 
It would thus be far more than an image of the universe, since to 
this it would add a second universe of self-formed ideas. In the 
third place, it would be infinitely capable of reproducing these 
ideas in outer nature, and thus bringing the universe into con- 
formity with itself. Man’s powers in this respect are limited, yet 
without changing place he has, by availing himself of the motor 
Principles and physical conditions of nature, a very extended 
Teach. As one example, by making the telegraph wire a virtual
