“Would I fortify myself against the fear of death, it must be at the expense of Seneca: would I extract consolation for myself or my friend, I must borrow it from Cicero.  I might have found it in myself, had I been trained to make use of my own reason.  I do not like this relative and mendicant understanding; for though we could become learned by other men's learning, a man can never be wise but by his own wisdom.”

“I have not seen anywhere in the world a more obvious malformed person and miracle than myself. Through use and time we become conditioned to anything strange; but the more I become familiar with and know myself, the more my deformity amazes me and the less I understand myself.”

“READER, You have here an honest book; it does at the outset forewarn You that, in contriving the same, I have proposed to myself no other than a domestic and private end: I have had no consideration at all either to Your service or to my glory. My powers are not capable of any such design. I have dedicated it to the particular commodity of my kinsfolk and friends, so that, having lost me (which they must do shortly), they may therein recover some traits of my conditions and humours, and by that means preserve more whole, and more life-like, the knowledge they had of me. Had my intention been to seek the world's favour, I should surely have adorned myself with borrowed beauties: I desire therein to be viewed as I appear in mine own genuine, simple, and ordinary manner, without study and artifice: for it is myself I paint. My defects are therein to be read to the life, and any imperfections and my natural form, so far as public reverence hath permitted me. If I had lived among those nations, which (they say) yet dwell under the sweet liberty of nature's primitive laws, I assure thee I would most willingly have painted myself quite fully and quite naked. Thus, reader, myself am the matter of my book: there's no reason You should employ Your leisure about so frivolous and vain a subject. Therefore farewell.”

“Learned we may be with another man's learning: we can only be wise with wisdom of our own.”

“To censure my own faults in some other person seems to me no more incongruous than to censure, as I often do, another's in myself. They must be denounced everywhere, and be allowed no place of sanctuary.”

“If I had even the slightest grasp upon my own faculties, I would not make essays, I would make decisions.”

“I find I am much prouder of the victory I obtain over myself, when, in the very ardor of dispute, I make myself submit to my adversary’s force of reason, than I am pleased with the victory I obtain over him through his weakness.”
