acoustical fact — a visible host and ail audible song ? ” “ If 
the former, the exaltation and the yearning are man’s imperish- 
able possession.” “If the latter, the belief in the entire 
transaction is wrecked by non-fulfilment.” 
This finishes the argument, if argument it may be called. 
The conclusion is summed up as already quoted : Thus, 
following the lead of physical science, we are brought without 
solution of continuity into the presence of problems which, as 
usually classified, lie entirely outside the domain of physics. 
To these problems thoughtful and penetrative minds are now 
applying those methods of research which in physical science 
have proved their truth by their fruit. There is on all hands a 
growing repugnance to invoke the supernatural in accounting 
for the phenomena of human life, and the thoughtful minds just 
referred to, finding no trace of evidence in favour of any other 
origin, are driven to seek in the interaction of social forces the 
c/enesis and development of man’s moral nature .” The careful 
reader will observe in these concluding words the affirmation 
for the first time in any of Prof. Tyndall’s writings, of the tenet 
that moral distinctions are the product of social agencies. 
That he must of necessity hold this opinion was clearly enough 
to be seen by any one who follows the logic of Atheistic Evo- 
lutionism, to which Prof. Tyndall professes that ho has been 
led with so many other thoughtful minds by scientific necessity. 
We have endeavoured to trace the successive steps by which 
Prof. Tyndall declares that he has been led to these conclusions. 
We have carefully stated his points, that we might candidly 
judge of the logical coherence and convincing force of the facts 
and analogies by which, “following the lead of physical science,” 
he has been brought first to face these problems, and then to 
solve them in these appalling answers : — Negatively there is no 
spirit, no freedom, no God, and no immortality, and positively 
the scientific and practical explanation of the past and the 
promise of the future lie in a blind force working under the 
law of progress for man’s amelioration, as the result of whose 
workings the idea of moral good is in due time developed, in 
whose name law is administered without justice. Morality as 
a social product creates religion which rules by relentless 
force without personal sympathy. As the result of the new 
solutions of these old problems, according to “ tlioso methods 
of research which in physical science have proved their truth 
by their fruit,” we are told that “ social duty will be raised to a 
higher level of significance, and the deepening sense of social 
duty will, it is to bo hoped, lessen if not obliterate the strifes 
and heart-burnings which now beset and disfigure our social 
life.”
