Evolution and its Consequences 9 1 



persuaded, however, that an intolerance which would exclude 

 from the band of ' loyal soldiers of science ' a Secchi, a Van 

 Beneden, and a Sullivan, merely because they happen to be 

 at the same time ' true sons of the Church,' will not commend 

 itself to the great bulk of my scientific fellow-countrymen 

 any more than the wish to deprive Catholics of their common 

 rights as citizens will be approved of by the English-speaking 

 races generally. 



Turning to Professor Huxley's observations in another 

 branch of philosophy, I proceed now to say a few words as to 

 his strictures on the psychology of the Quarterly RevicAver. 



I apprehend that my critic's psychological views coincide 

 in the main with those of Mr. Herbert Spencer. Now it is 

 not of course possible within the limits of this article to write 

 a treatise on psychology, and nothing less would be requisite 

 to explain the grounds of my complete and fundamental 

 divergence from the views referred to. It must suffice to say 

 here, that Professor Huxley has adduced no argument and 

 has brought forward no kind of illustration which I have not 

 maturely considered and deliberately rejected as inadequate 

 and fallacious. Another time I hope to be able to go at 

 length into this question and to endeavour to explain, 

 according to the system I adopt, the facts adduced by the 

 opposite school; as also to support my views by positive 

 arguments. In the meantime I heartily re-echo Professor 

 Huxley's tribute to the supreme importance of ' the philoso- 

 phical questions which underlie all physical science,' and I am 

 confident that vast good would result if only men could be 

 brought to undergo the labour and persevering application 

 necessary for their thorough investigation. 



I must here, then, confine myself to the clearing up of 

 some misapprehensions and misrepresentations. 



In the first place. Professor Huxley objects to the asser- 

 tion that 'sensation' is not 'thought,' 'though sensations
