105. The internal of thought is from the life's love and its affections and consequent perceptions; while the external of thought is from the contents of the memory which minister to the life's love as confirmations and as means to further its end. From infancy to the age of youth man is in the external of thought from an affection for knowing, which then constitutes its internal. There also emerges from his life's love, which is innate from his parents, something of its lust and consequent inclination. Later, however, his way of life determines his life's love, and its affections and consequent perceptions constitute the internal of his thought. From his life's love there is formed the love of means; and their delights with the knowledges thereby called forth from the memory constitute the external of his thought.
