addition quotes

And if there be any addition to knowledge, it is rather a new knowledge than a greater knowledge; rather a singularity in a desire of proposing something that was not knownat all beforethananimproving, anadvancing, a multiplying of former inceptions; and by that means, no knowledge comes to be perfect.

-John Donne
