I.

Fear, love, joy, sadness, lust, eager desire, anger, pity, emulation, admiration,--these motions or affections of the mind exist from the beginning of man's creation by the Lord; and they were usefully and advantageously introduced into human nature, that by governing himself by these with method, and in accordance with reason, man may be able, by acting manfully, to exercise those good qualities, by means of which he would justly have deserved to receive from the Lord eternal life. For these affections of the mind being restrained within their proper limits, that is, being rightly employed, produce at present good qualities, and in the future eternal rewards. But when they advance [^2004] beyond their boundaries, that is, when they turn aside to an evil course, then vices and iniquities come forth, and produce everlasting punishments. [^2005]
