Which detail best reveals Theseus's determination?


(5) And (when his eighteenth year was past), Aithra led him up again to the temple, and said, 'Theseus, lift the stone this day, or never know who you are.' And Theseus went into the thicket, and stood over the stone, and tugged at it; and it moved. Then (his spirit swelled within him), and he said,'(If I break my heart in my body, it shall up).' And (he tugged at it once more, and lifted it), and rolled it over with a shout.
