About Filling A Commonplace Book?

I go here and there, culling out of several books the sentences that best please me, not to keep them (for I have no memory to retain them in), but to transplant them into this; where, to say the truth, they are no more mine than in their first places. 

Michel de Montaigne

For decades he had acted in the belief that his intellect and sensibility led him to reject a world whose products were unbearable to either intellect or sensibility, but were always available for criticism by the same.... such mad grandiosely dignified declarations could hardly be regarded as anything but eccentric.  However, this did not stop him making them.
