La duda, Marble sculpture group in Plaza San Martín, Argentina.

La Duda is a marble sculpture group in Plaza San Martín depicting figures lost in deep thought. The work impresses through carefully crafted details that reflect concentration and inner tension in the faces and postures of the figures.

In 1905 the Municipality of Buenos Aires sent a commission to Europe to buy sculptures for its plazas, which had almost none; Manuel G. Güiraldes acquired this work by French sculptor Louis Henri Cordier (1853–1925). It was installed in Plaza San Martín between 1905 and 1906. Some predicted it would be rejected for questioning biblical themes, but it never provoked religious disputes.

The work's title, Le doute, is carved into the rocky outcrop the two figures sit on, so the theme is stated in the stone itself. When the piece was installed in 1905–1906, some predicted protests over a subject questioning biblical teaching; none came, and it never sparked a religious dispute.

The sculpture group sits in Plaza San Martín and is freely accessible throughout the day. You can view it easily from the surrounding area at various angles, with different lighting effects on the marble depending on the time of day.

The words "Le doute" are carved into the rocky outcrop the two figures sit on, not on a separate plaque. The sculpture was bought in Europe by Manuel G. Güiraldes for the city's 1905 purchase of plaza ornaments, and it stands about 20 metres from the Santa Fe avenue sidewalk.
