The 18th century British society witnessed subtle and profound changes in 'structures of feeling'.In the Age of Enlightenment, the aristocratic elite tried to coexist with the middle classes, overseas adventures pioneered colonial expansion, the grand tour and home travels developed and promoted each other, and the travel literature played an important role in the shaping of new structures of feeling which turned from the classical aesthetic ideal of symmetry and balance to sublime and grandeur, and from rationalism to sentimentalism.Continual travels wakened the traveler's cultural perception and sensitivity, stimulated his capability of empathy, renewed his cultural experience, and deepened his self-cognition.With frequent changes in time and space the traveler dodged all fixed roles and definitions, going further and further on the way of self-discovery and self-identification.With the passage of time, the growth of subjectivity in structures of feeling would find its next page and high tide in the approaching Age of Romanticism.
