Shews, in the example of Natura, how from our very birth, the passions, to which the human soul is incident, are discoverable in us; and how far the organs of sense, or what is called the constitution, has an effect over us, Page 4. CHAP. II. Contains some proofs by what swift degrees the passions gain an ascendant over the mind, and grow up in proportion with our reason, Page 7. CHAP. III. The early influence which the difference of sex excites, is here exemplified, in the fond, but innocent affection of Natura and Delia, Page 21. CHAP. IV. Shews, that till we arrive at a certain age, the impressions made on us are easily erased; and also that when those which bear the name of love are once rooted in the mind, there are no lengths to which we may not be transported by that passion, if great care is not taken to prevent its getting the ascendant over reason, Page 27. CHAP. V. That to indulge any one fault, brings with it the temptation of committing others, is demonstrated by the behaviour of Natura, and the misfortunes and disgrace, which an ill-judged shame had like to have involved him in, Page 39. CHAP. VI. Shews the great force of natural affection, and the good effects it has over a grateful mind, Page 51. BOOK the Second. CHAP. I. The inconsideration and instability of youth, when unrestrained by authority, is here exemplified, in an odd adventure Natura embarked in with two nuns, after the death of his governor, Page 63. CHAP. II. The pleasures of travelling described, and the improvement a sensible mind may receive from it: with some hints to the censorious, not to be too severe on errors, the circumstances of which they are ignorant of, occasioned by a remarkable instance of an involuntary slip of nature, Page 99. CHAP. III. The uncertainty of human events displayed in many surprizing turns of fortune, which befel Natura, on his endeavouring to settle himself in the world: with some proofs of the necessity of fortitude, as it may happen that actions, excited by the greatest virtue, may prove the source of evil, both to ourselves and others, Page 108. CHAP. IV. The power of fear over a mind, weak either by nature, or infirmities of body: The danger of its leading to despair, is shewn by the condition Natura was reduced to by the importunities of priests of different perswasions. This chapter also demonstrates, the little power people have of judging what is really best for them, and that what has the appearance of the severest disappointment, is frequently the greatest good, Page 135. CHAP. V. Shews that there is no one human advantage to which all others should be sacrificed:--the force of ambition, and the folly of suffering it to gain too great an ascendant over us:--public grandeur little capable of atoning for private discontent; among which jealousy, whether of love or honour, is the most tormenting, Page 154.
