Final answer:
Wassily Kandinsky switched his career from law to art due to his profound interest in the spiritual impact of color on the soul.
Step-by-step explanation:
Wassily Kandinsky, originally trained in law, experienced a profound artistic transformation that led him to switch his career path to art. His early fascination with color and its spiritual impact on the soul compelled him to pursue artistic studies in Munich, after declining a teaching position post-graduation. Kandinsky's quote, "Colour is the keyboard, the eyes are the hammers, the soul is the piano with many strings. The artist is the hand that plays, touching one key or another, causing vibrations in the soul," captures his philosophical approach to art. Following World War I and the Bolshevik Revolution, Kandinsky established a museum of art in Moscow, but subsequently found himself at odds with the materialism of the Soviet regime. His ongoing conflicts and the oppressive political climate of 1923 Russia, marked by poverty and censorship, ultimately compelled him to leave and continue his career in France, further developing his reputation as an innovative painter.
