Abstract:If "the issue of moral legitimacy in the context of historical materialism" is called the initial issue of bet365 games，Then，Can bet365 games itself be regarded as a knowledge、Established as a serious science，That is, "the intellectual legitimacy problem of bet365 games itself"，is more forward、A more fundamental problem。Pre-questions are not equal to initial questions。Because of Marx and Engels’ denial and criticism of morality，Not enough to constitute a reason why bet365 games is not valid。Fundamentally，Does bet365 games have intellectual legitimacy，Related to whether Marxists (especially their classic writers) systematically talk and think about moral phenomena or moral issues，Related to whether Marxist theory contains or points to ethical normativity，Related to whether there are moral problems in real life and whether Marxists intend to use Marxist theory to deal with these problems。When Marxist moral discussion lacks systematicity, which prevents us from extracting clear value demands and reasonable paths of realization，or，When the interpreter gives it too much normative character，So much so that it breaks through the boundaries of historical materialism，Only will bring a negative answer to the prerequisite questions of bet365 games。
