The author of the article analyzes dialogues of the first book of the treatise by Petrarch "Phisicke Against Fortune" (1354—1366). The author considers that the subject of emotions, human passions, private and public feelings passes through all the treatise. The article reveals that passions (Joy, Hope, Grief, Fear) are characterized as enemies of mind in prefaces. The world of feelings appears there as the world of reactions to instability of human life circumstances. At the level of anthropological judgments Petrarch looks at the human, as at a creature, which is inconsistent in emotions by its nature. The author defined among emotions several types: social and status, family, personal, leisure and esthetic. She analyzed them on the example of separate dialogues (I, 28, 40—42, 53—56, 69, 71, 83—84). The main conclusions: every third (of 51) dialogue is connected with social emotions (the power, an origin, richness, housekeeping). They show new mental settings, draw new behavior models: citizen feels like a hero of the time. The structure and nature of family pleasures (18 in total) comprises a powerful "universal" component. "Customs of the century" are in that fact that our characters tell us only about father`s feelings, forgetting about mother. In the center of attention - the world of father`s emotions. In general emotions of characters are in the secular, social, daily or festive sphere of life; they almost don't concern the religious world of the personality, pleasures of service to Christ.
