I need to choose which 5 of these are antithesis. Please tell me if i'm correct. I put a star next to them.

*A little learning is a dangerous thing, drinking deep or taste not the pierian spring

*be not the first by whom the new are tried, nor yet the last to lay the old aside

*true ease in writing comes from art, not chance as those move easiest who have learned to dance.

be thou the first true merit to befriend, his praise is lost, who stays till all commend.

*good nature and good sense must ever join; to err is human, to forgive, divine.

hope springs eternal in the human breast; man never is, but always to be blest.

'tis education forms the common mind, just as the twig is bent, the tree's inclined

*but when to mischief mortals bend their will, how soon they find fit instruments of ill!
