What are the differences between classicism, romanticism and realism?

The basis of classicism was rationality, the belief that the world was reasonably structured on the whole, and all its shortcomings could be corrected by the power of the human mind. Reasonable – this means clearly, harmoniously, harmoniously. That was the art of classicism. It strove for ideal proportions and shapes, often aligning itself with antique patterns,
Proponents of romanticism opposed reason with sense, civilization with nature, clarity with mystery and understatement. From the “desert of reason” of classicism, romantics led their viewers and readers into the unknown – to where freedom is hidden. They looked for her in the distant past, in folk art, in exotic countries. The central figure of creativity was a romantic hero – lonely, proud and misunderstood.
In contrast to; classicists, and from romanticism, proponents of realism sought to accurately reflect the world around them, to the “truth of life.” In this they saw the value of art. Realists often acted as critics of contemporary society, showing its vices and illnesses, making us think about their treatment.
