Everyone has biases, always, & it’s OK to have biases.
And the mitigation, reduction and transcendence of biases that is prescribed by rationalism – by the ideals/principles of rationality – is folly.
[A proponent of ideals of rationality may reply that this results in pure relativism, ]but actually this needn’t/doesn’t result in relativism:
What’s important isn’t whether one has biases, but whether one’s biases are fixed* or can move, i.e. whether there is a dogma that is a/the fixed (and oft-unnoticed) source of one’s biases or whether one[‘s mind] is open to dialectic, unconstrained movement of ideas & evolution of theories/paradigms & organic growth and development of the overall ideological/theoretical/philosophical [meta-]structure…
I’m suggesting a mode of thinking that results not in biases being reduced [until they maybe disappear], but instead results in uncovering of a bias going hand-in-hand with a new, biased part of theory/mind being produced** – of which the bias later should/can be uncovered… So this is a step-wise, indefinitely continuing process by which a theory or mind or philosophy organically changes and grows.
And maybe on the meta-level I’m distinguishing between two ways of thinking/doing philosophy: seeing biases as negative or seeing them as interesting and as a necessary component of any temporary theory that one uses before one has reached the totality [of knowledge] (which of course nobody has and is indefinitely far in the future…
*if they are fixed, and one insists on reduction of bias, then the result is denial.
**meanwhile, the part/structure of theory/mind that one has found a bias in isn’t sanitized and maintained – it is commensurately exited/abandoned as one’s ideas move and one’s mind shifts to a new theory – the shifting of biases is a logical result of the movement/change of ideas. (or it is (temporarily) accepted along with its bias…)
