Preface 
Gone desire has been expressed for the 
publication in a conveniently accessible 
form of the particular addresses and essays 
which this little volume contains. They have 
all appeared before in books or magazines, 
but they have not been arranged collectively. 
This has now been done, and, for what they 
are worth, the contents of this book are now 
assembled as containing an expression of faith, 
in knowledge, in higher education, and in 
a special phase of the unwritten Constitution 
of the Empire. 
HALDANE.
