Others with broader thought—although having no 
knowledge of life independent of matter—exclaim with 
Tyndall—‘‘ Here the vision of the mind authoritatively 
supplements the vision of the eye. By an intellectual 
necessity I cross the boundary of the experimental evi- 
dence, and discern, in that matter which we, in our ig- 
norance of its latent powers, and notwithstanding our 
professed reverence for its creator, have hitherto covered 
with opprobrium—the promise and potency of all 
-terrestrial life.’ But listen—he further says—‘‘ Our 
states of consciousness are symbols of an outside entity 
which produces them and determines the order of their 
succession, but the real nature of which we can never 
know. In fact the whole process of evolution is the 
manifestation of a power absolutely inscrutable to the 
intellect of man,” ‘‘as little in our day, as in the days 
of Job, can man by searching find this power out.”’ 
This is an expression of intellectual integrity exceed- 
ingly refreshing to reflecting minds, for, while within 
the limits of the material world everything is seen 
originating from physical antecedents, by methods so 
uniform and invariable that we call these methods 
‘““laws,’’ there is nevertheless an existence of some 
reality, some inscrutable power back of all matter and 
all force, in relation to which no predicatecan be formed. 
Philosophy and science are in accord concerning the 
existence of a reality beyond the material expressions 
of nature, as revealed to the human mind, and it re- 
mains to ask if this reality is an intelligence that oper- 
ates, as an efficient cause, through definite means to the 
attainment of definite ends ? 
This must be answered by the evidences of design as 
manifested in the universe. 
The testimony given by nature is, however, suscepti- 
ble of different interpretations according to the stand- 
point of the observer, which enables him to behold
