There is also much confusion about what it means to speak with scientific “objectivity.” There are two very different senses of the terms “objective” and “subjective.”
The first relates to how we know (i.e. epistemology), the second to what there is to know (i.e. ontology). When we say that we are reasoning or speaking “objectively,” we mean that we are free of obvious bias, open to counter-arguments, cognizant of the relevant facts, etc. There is no impediment to our doing this with regard to subjective (i.e. first-person) facts.
