The intellectual attainments of a man who thinks for himself resemble a fine painting, 

where the light and shade are correct, 

the tone sustained, 

the colour perfectly harmonised; 

it is true to life. 

On the other hand,

 the intellectual attainments of the mere man of learning are like a large palette,

 full of all sorts of colours, 

which at most are systematically arranged

, but devoid of harmony, connection and meaning
