I’ve heard it put this way: either you have an ideology, or an ideology has you.
In other words, it’s better to be actively engaged in a particular way of how you’re looking at things, knowing what biases you’re bringing, otherwise it’s being done for you through some cultural apparatus and you will wrongfully assume yourself to be unbiased. Knowing how your particular ideology works takes much more effort, as does any form of introspection, since you have to truly examine your values and make choices, so even then part of it would still be unconsciously influenced by culture since alternatives are rarely, if ever offered.
