"The enmity of such a party towards Socialism does not mean that the members are only prejudiced against it because they do not know it; it means that they are possessed of bourgeois ideas, and wish to determine their policy accordingly"

In the quote by Karl Radek, he calls attention to the deep-seated opposition of certain groups, especially those lined up with bourgeois interests, towards socialism. This enmity, Radek implies, is not a simple result of lack of knowledge or misunderstanding of socialist concepts, but rather originates from an essential distinction in ideological convictions and class interests.

Radek refers to "such a party", likely pointing to political groups or factions representing bourgeois or capitalist interests. His assertion is that their opposition to socialism is not due to an absence of familiarity or knowledge. Instead, it develops because these groups inherently embody and promote bourgeois concepts-- those that prioritize specific wealth build-up, private property, and market-driven economies. Such concepts are in direct dispute with socialist concepts, which promote for collective ownership, social equality, and resource redistribution.

By "had of bourgeois ideas", Radek suggests that these parties are directed by beliefs that sustain the existing capitalist structure, from which they benefit. Their policies reflect a dedication to preserving the status quo that guarantees the supremacy of bourgeois classes, therefore opposing socialist perfects that challenge and threaten this supremacy by promoting economic and social reforms targeted at decreasing inequality.

Radek's quote underscores the struggle in between varying social classes and their particular ideologies. It highlights how the concerns of a specific class shape its political agenda and reactions to social modification. The bourgeoisie's resistance to socialism is, therefore, a defensive stance to secure their interests and power against the prospective turmoil assured by socialist reforms.

In essence, Radek's declaration is an observation of how class dynamics and beneficial interests influence political ideologies and policies. This insight acts as a suggestion of the intricacies in ideological battles where underlying class interests often drive the opposition, making it a more formidable force than if it were merely based upon lack of knowledge.
