insured by multiplying the number, intensity, and variety of 
his experiences. Spinoza had fora motto, “to live is to think.’ 
Surely the quantity and quality of our thinking has much to _ 
do with the quantity and quality of our living, but from con- 
siderations already discussed, this utterance seems to be want- 
ing in comprehensiveness. If this statement were true without 
qualifications, then he who thinks most lives most, but we 
have already seen that other experiences than those of thought 
have perhaps an equal degree of intensity, and involve an 
equal amount ofliving. Any conclusion which can be reached — 
on this question is necessarily colored by personal prejudices, 
and cannot be set up as a general standard. To me, at least, ` 
he seems to live most who enjoys the greatest possible range 
of conscious experiences of the highest order, during the long- — 
est period of time. And the quantity of life seems to be truly 
greatest which embodies the fullest and highest expression of | 
the attributes of the intellect, the emotions and the will. : 
Not where the experiences are confined to one of these 
alone, but where all three have equal sovereignty in the 
dominion of the mind. He seems to me. to live less whose 
life embodies one or all of these in a less degree, or who has 
sullied their original purity with baser purposes and ends. 
Perhaps this may seem too ethical for a scientific statement 
but until that same ethical spirit shall more fully actuate the 
promoters of science, its highest beauty and usefulness cannot — 
be completely realized. Even the best of us lead much more — 
diminutive lives than our circumstances require. 
but remember that it is as easy to think great thoughts as w 
think little thoughts, and feel great emotions instead of base 
and belittling ones, we might all enter into a largeness í 
life which far exceeds its present dimensions. But we must 
pass on to consider the question how can the race live most? 
One thing is certain, while all are permitted to think and fi 
and will, all cannot be brain workers. There must be doers 
as well. Society is so organized that no small part of 
members must perform physical labor. This being the case, 
to realize the maximum of conscious life, there must be 1 
greatest possible number of mental laborers, and the least po
