 Consider reductionism and foundationalism. While it cannot be denied that various reductionist projects were at one time or another undertaken by members of the Vienna Circle and that not all of its members were epistemological anti-foundationalists either from the start or at the end, it is clearly false to paint all of them with reductivist and/or foundationalist brushes. This is particularly true of the members of the so-called left wing of the Circle, all of whom ended up with anti-foundationalist and anti-reductionist positions (even though this did involve instrumentalism for some).
