 
Born in Königsberg, Jacoby studied Protestant theology there from 1900 to 1903. He acquired the licentiate degree with a text interpretation of the Biblical book of Jeremiah. After the state examination for the higher school service in religion, Hebrew and German, which he passed in 1904, he studied philosophy in East Prussia and Berlin while working as an assistant teacher and received his doctorate in 1906 under Friedrich Paulsen with the work Herders "Kalligone" und ihre Verhältnis zu Kants "Kritik der Urteilskraft". Two years as an exchange teacher in Paris and Glasgow followed and in 1908 a failed habilitation attempt in Münster. Finally Jacoby habilitated 1909 in Greifswald with his book Herders und Kants Ästhetik published two years before and based on his dissertation as well as the manuscript Die Philosophie Herders.

After completing his habilitation, Jacoby became a private lecturer in philosophy at Greifswald University. Jacoby's inaugural Greifswald lecture on pragmatism resulted in a correspondence with William James, which led to an invitation as a Research Fellow at Harvard University. In 1911 he presented the work Herder als Faust, in which he attempted to demonstrate by comparing texts that Johann Wolfgang von Goethe had Johann Gottfried Herder in mind as a model for his Faust drama. After a visiting professorship at the University of Illinois and extensive lecture tours in Asia and North Africa, Jacoby served for several months as a war volunteer officer on the Western Front before he was seriously wounded and, deemed as unfit for service, dismissed with the Iron Cross second class. In 1915 the Prussian Ministry of Culture recruited lecturers for the newly founded Istanbul University, and Jacoby taught there until November 1918, "using the amply granted leisure time for a never published opus on Herder and the New Foundation of German Philosophy in the Second Half of the 18th Century".

After his return, Jacoby joined the West Russian Volunteer Army but soon returned to Greifswald at the beginning of the summer semester 1919. In March 1920 he took part in the leadership of a volunteer company in the Kapp Putsch against the Weimar Republic. After the rapid failure of this uprising "Jacoby followed old sympathies only as a voter of the DNVP and dedicated himself to his life's work, the ontology of reality".
