But they themselves had their separate functions and duties. Some had the faculty of order exceptionally developed; and they were the classifiers of the community and of the work of the community. Others had the logical powers in especial vigour; and they followed out the philosophy of the race, the correlation of the ideas and of the lines of reasoning. A third group consisted of those with a dominant imagination; these looked into the future; they performed some of the functions of imaginative writers in Europe, sketching out imaginary routes for the race and for each family into the unknown; but they also covered a much wider field; they put into form and expression schemes and projects such as European men of action of the most romantic careers have often attempted to carry out, but have seldom been able to put into words; these were not allowed to interfere with action, but the ideas, plans, and romances they invented and put into shape were tested and accepted or rejected by the practical men whose sphere they touched. Imagination, it was held by the Limanorans, was apt to be a futile, if not mischievous, faculty through want of its being ranged on the side of utility; and yet, if trammelled and yoked to the necessity of practice in the individual, it came to be stifled. They specially cultivated it in these families in order that it should have full scope and development, but took care, by ranging these families with those that superintend the purpose and progress of the race, that their romances should have full relevancy to the goal of all their efforts. Many of the projects and ideas which seemed at first the most fantastic were found after many generations to be sound and most possible of realisation.
