only what it is, a superfluity, and desires only to remain in hiding". On 16 October 1843, Kierkegaard published three more books about love and faith and several more discourses. Fear and Trembling was published under the pseudonym Johannes de Silentio. Repetition is about a Young Man (Søren Kierkegaard) who has anxiety and depression because he feels he has to sacrifice his love for a girl (Regine Olsen) to God. He tries to see if the new science of psychology can help him understand himself. Constantin Constantius, who is the pseudonymous author of that book, is the psychologist. At the same time, he published Three Upbuilding Discourses, 1843 under his own name, which dealt specifically with how love can be used to hide things from yourself or others. These three books, all published on the same day, are an example of Kierkegaard's method of indirect communication. Kierkegaard questioned whether an individual can know if something is a good gift from God or not and concludes by saying, "it does not depend, then, merely upon what one sees, but what one sees depends upon how one sees; all observation is not just a receiving, a discovering, but also a bringing forth, and insofar as it is that, how the observer himself is constituted is indeed decisive." God's love is imparted indirectly just as our own sometimes is. During 1844, he published two, three, and four more upbuilding discourses just as he did in 1843, but here he discussed how an individual might come to know God. Theologians, philosophers and historians were all engaged in debating about the existence of God. This is direct communication and Kierkegaard thinks this might be useful for theologians, philosophers, and historians (associations) but not at all useful for the "single individual" who is interested in becoming a Christian. Kierkegaard always wrote for "that single individual whom I with joy and gratitude call my reader"; the single individual must put what is understood to use or it will be lost. Reflection can take an individual only so far before the imagination begins to change the whole content of what was being thought about. Love is won by being exercised just as much as faith and patience are. He also wrote several more pseudonymous books in 1844: Philosophical Fragments, Prefaces and The Concept of Anxiety and finished the year up with Four Upbuilding Discourses, 1844. He used indirect
