Nor was his home training, formidably abstract, counterbalanced by a normal, healthy school-life. Naturally introspective and shy, both on account of a slight deformity of his body and on account of the old-fashioned clothes his father made him wear, he had no boy friends; and when cuffed by his more robust contemporaries, he could defend himself only with his biting sarcasm. Notwithstanding his early maturity he does not seem to have impressed either his schoolmates or his teachers by any gifts much above the ordinary. The school he attended was one of those semi-public schools which by strict discipline and consistent methods laid a solid foundation of humanities and mathematics for those who were to enter upon a professional career. The natural sciences played noddle whatever. Obedient to the wishes of his father, Sören chose the study of theology, as had his eldest brother; but, once relieved from the grind of school at the age of seventeen, he rejoiced in the full liberty of university life, indulging himself to his heart's content in all the refined intellectual and æsthetic enjoyments the gay capital of Copenhagen offered. He declares himself in later years to be "one who is penitent" for having in his youth plunged into all kinds of excesses; but we feel reasonably sure that he committed no excesses worse than "high living." He was frequently seen at the opera and the theatre, spent money freely in restaurants and confectionary shops, bought many and expensive books, dressed well, and indulged in such extravagances as driving in a carriage and pair, alone, for days through the fields and forests of the lovely island of Zealand. In fact, he contracted considerable debts, so that his disappointed father decided to put him on an allowance of 500 rixdollars yearly--rather a handsome sum, a hundred years ago. Naturally, little direct progress was made in his studies. But while to all appearances aimlessly dissipating his energies, he showed a pronounced love for philosophy and kindred disciplines. He lost no opportunity then offered at the University of Copenhagen to train his mind along these lines. He heard the sturdily independent Sibbern's lectures on æsthetics and enjoyed a "privatissimum" on the main issues of Schleiermacher's Dogmatics with his later enemy, the theologian Martensen, author of the celebrated "Christian Dogmatics."
