Never mind the manner, which may or may not be good; but think only of the truth of my words, and give heed to that: let the speaker speak truly and the judge decide justly.†

heed = pay close attention to; or do what is suggested
but I shall obey God rather than you, and while I have life and strength I shall never cease from the practice and teaching of philosophy, exhorting any one whom I meet and saying to him after my manner: You, my friend,—a citizen of the great and mighty and wise city of Athens,—are you not ashamed of heaping up the greatest amount of money and honour and reputation, and caring so little about wisdom and truth and the greatest improvement of the soul, which you never regard or heed at all?†
