Meaning: The quote "This is the absolute truth: and on this truth our tactics must be based. All tactics that are not based on this are false, and lead the proletariat to terrible defeat" is attributed to Herman Gorter, a Dutch poet who was also known for his involvement in socialist and communist movements. The quote reflects Gorter's belief in the importance of truth and its alignment with the tactics employed by the proletariat in their struggle for social and economic justice.

Herman Gorter was a prominent figure in the early 20th-century socialist and communist movements, particularly in the Netherlands. He was a member of the Social Democratic Workers' Party (SDAP) and later became associated with the radical left-wing of the movement, advocating for more revolutionary tactics to achieve socialist goals.

The quote can be interpreted in the context of Gorter's commitment to the principles of Marxism and his belief in the necessity of a clear and truthful understanding of the social and economic conditions that the proletariat faced. Gorter's emphasis on "absolute truth" suggests a rejection of tactics based on deception or compromise, instead advocating for a principled and uncompromising approach to class struggle.

In the context of socialist and communist movements, the "tactics" referred to in the quote encompass a wide range of strategies and methods employed by the working class to challenge and ultimately overthrow the capitalist system. These tactics could include political organizing, strikes, demonstrations, and revolutionary action aimed at achieving the emancipation of the proletariat.

Gorter's warning about tactics that are "not based on this truth" leading to "terrible defeat" underscores his conviction that a clear understanding of the fundamental social and economic relations is essential for the success of the proletariat's struggle. In this sense, he highlights the danger of adopting tactics based on illusions or misconceptions, which may ultimately undermine the revolutionary aspirations of the working class.

Furthermore, the reference to "the proletariat" in the quote reflects Gorter's identification with the working-class movement and his commitment to advancing its interests. As a poet and intellectual, Gorter sought to articulate the experiences and aspirations of the proletariat through his writings and political activism, aligning himself with the cause of social and economic justice.

Gorter's quote can also be seen as a critique of opportunism and reformism within the socialist movement, as he emphasizes the necessity of basing tactics on the "absolute truth" rather than compromising with the existing power structures. His stance aligns with the revolutionary currents within Marxism that sought to challenge the status quo and push for radical transformation.

Overall, Herman Gorter's quote encapsulates his unwavering dedication to the pursuit of truth and its alignment with the tactics employed by the proletariat in their struggle for liberation. It reflects his commitment to revolutionary principles and his rejection of tactics that deviate from the fundamental truths underlying the class struggle. In the broader context of socialist and communist movements, Gorter's words continue to resonate as a reminder of the importance of ideological clarity and principled action in the pursuit of social change.
