They have unacknowledged philosophical opinions about philosophy!! Everything most scientists study is "beneath' them., it is pure matter whereas they are not pure matter. They have freedom, intellect, the ability to know the world. It is the degrading of self to the level of a purely material being that paves the way for that view of 'philosophy' But it is a false view for sure.
“Let us not pretend to doubt in philosophy what we do not doubt in our hearts." C S Peirce
