Courbet painted figurative compositions, landscapes, seascapes, and still-lifes. He courted controversy by addressing social issues in his work, and by painting subjects that were considered vulgar, such as the rural bourgeoisie, peasants, and working conditions of the poor. His work belonged neither to the predominant Romantic nor Neoclassical schools. History painting, which the Paris Salon esteemed as a painter's highest calling, did not interest Courbet, who stated that "the artists of one century [are] basically incapable of reproducing the aspect of a past or future century ..."[2] Instead, he believed that the only possible source for living art is the artist's own experience.[2] His work, along with that of Honoré Daumier and Jean-François Millet, became known as Realism. For Courbet realism dealt not with the perfection of line and form, but entailed spontaneous and rough handling of paint, suggesting direct observation by the artist while portraying the irregularities in nature. He depicted the harshness in life, and in so doing challenged contemporary academic ideas of art.
