Classical German philosophy of the 18th and 19th centuries had a significant influence on the development of psychology during this period. This philosophical movement was characterized by an emphasis on reason and the importance of individual freedom and autonomy, and these themes were reflected in the early psychological theories that emerged from this philosophical movement. One of the most significant figures in this movement was Immanuel Kant, considered by many to be one of the most important philosophers in history. Kant's emphasis on the importance of individual autonomy and the role of reason in human cognition had a profound influence on the emerging field of psychology. In particular, his idea of ​​the transcendental self, which holds that the self is the unifying principle of all experience, provided an important conceptual framework for understanding the role of the self in psychological processes. Another key figure of the classical German philosophical movement was Johann Wolfgang von Goethe. Goethe's work in the natural sciences, especially botany and geology, had a significant influence on the emerging field of psychology. His emphasis on the interconnectedness of all natural phenomena and his belief in the importance of a holistic approach to understanding complex systems were reflected in early psychological theories that emphasized the interactions between various psychological processes. Perhaps the most important figure in the classical German philosophical movement was Friedrich Nietzsche. Nietzsche's emphasis on the importance of individual freedom and rejection of traditional moral and religious systems had a profound impact on the emerging field of psychology. His ideas about the will to power and the importance of self-transcendence laid the foundation for understanding the role of individuality in psychological processes. Other important figures in this movement included Georg Wilhelm Friedrich Hegel, whose dialectical approach to understanding reality influenced early psychological theories that emphasized the interaction between various psychological processes ; Arthur Schopenhauer, whose emphasis on the importance of the will in human behavior provided the basis for understanding the role of motivation in psychological processes; and Carl Gustav Jung, whose work on archetypes and the collective unconscious provided a new way of thinking about the role of unconscious processes in psychological development. Overall, the classical German philosophical movement had a profound influence on the development of psychology in the 18th and 19th centuries. His emphasis on reason, individual freedom, and autonomy provided a framework for understanding the complex interaction of various psychological processes, and his rejection of traditional moral and religious systems paved the way for new approaches to understanding human behavior and psychological development. Today, the legacy of this philosophical movement can still be seen in many of the most important theories and concepts in psychology, making it a lasting and important influence on the field.
