In relation to St. John Rivers, Jane states:
Had he been a statue instead of a man, he could not have been easier. He was young-- perhaps from twenty-eight to thirty--tall, slender; his face riveted the eye; it was like a Greek face, very pure in outline: quite a straight, classic nose; quite an Athenian mouth and chin. It is seldom, indeed, an English face comes so near the antique models as did his. He might well be a little shocked at the irregularity of my lineaments, his own being so harmonious. His eyes were large and blue, with brown lashes; his high forehead, colourless as ivory, was partially streaked over by careless locks of fair hair.
This is a gentle delineation, is it not, reader? Yet he whom it describes scarcely impressed one with the idea of a gentle, a yielding, an impressible, or even of a placid nature. Quiescent as he now sat, there was something about his nostril, his mouth, his brow, which, to my perceptions, indicated elements within either restless, or hard, or eager.
Based on this description, what is Jane's overall opinion of St. John?
