Between 1842 and 1844, Kapp studied law and philosophy at the University of Heidelberg. There, at his uncle Christian Kapp's (1798–1874) house, he met the philosopher Ludwig Feuerbach. Not only did they become close friends; Feuerbach's criticism of religion, which also strongly influenced Karl Marx, had a great impact on Kapp's attitude towards life as well. Other acquaintances from his time as a student were Ludwig Bamberger (1823–1899), who would later become a banker, the author Berthold Auerbach (1812–1882) of Heidelberg and the poet Bettina von Arnim (1785–1859) of Berlin.

 Passage 3:The Ottomans fought for three centuries to destroy the Christian-Georgian consciousness of the Laz people. Due to the Ottoman Islamization policy, throughout of seventeenth century Lazs gradually converted to Islam. As the Ottomans consolidated their rule, the Millet system was brought to the newly conquered territories. Local orthodox inhabitants, once subordinated to the Georgian Orthodox Church, had to obey Patriarchate of Constantinople, thus gradually becoming Greeks, the process known as Hellenization of Laz people. Lazs who were under the control of Constantinople, soon lost their language and self-identity as they became Greeks and learned Greek, especially Pontic dialect of Greek language, although native language was preserved by Lazs who had become Muslims. In the middle of the seventeen century, several governors of Tunis, who bore the title of Dey were Laz origin, such as: Muhammad Laz (1647-1653), Mustafa Laz (1653-1665) and Ali Laz (1673).
