Hylo -Idealism, or the Egoistic Theory of Mind and Matter. By 
R. Lewins, M.D. 
Our attention has been called to the above paper, which appears 
in the “ Secular Review,” especially as it is a kind of summing 
up of ideas which first appeared in our pages under the title 
“ Hylo-Phenomenonalism the Summa Scientias.” The author’s 
views, as here expressed, border very closely upon those of the 
mediaeval nominalists, Abelard and Occam, the difference being 
simply the outcome of the advances made in Science since the 
thirteenth century. 
Dr. Lewins hopes that his views may ultimately prove an 
Eirenicon, reconciling the scientific and the poetic interpretations 
of Nature, and finally eliminating all ontological tendencies. 
However this may be, it cannot be other than wholesome for the 
public to be reminded of the assumption underlying all Science. 
We know that our sensations of colour, form, sound, odour, &c., 
are merely impressions, i.e., changes in our own mind. We 
postulate these changes as due to and as corresponding with the 
existence and the changes in an external world. But both in 
scientific research and in the practice of daily life we forget too 
often that all this is an assumption which — be it truth or error- — 
is incapable of demonstration. 
Was John Bunyan a Gipsy ? By James Simson. New York : 
James Miller. Edinburgh : Maclachlan and Stewart. 
We received some time ago a pamphlet by the same author, on 
the same subjedt, and pronounced it as entirely outside our 
competence. We can merely repeat that the nationality of John 
Bunyan does not concern the ‘‘Journal of Science.”
