Seems to me that the label "rationalist" is one that facilitates a group bias. It lends weight to the view that those who aren't "rationalists" can't be rational.

Seems to me that it is reasonable to be less firm in holding to rationalism than stating... "I am a rationalist". For that's about all that the person is, it demands a total commitment to rational thinking and feeling and thence sets one up for failure. How high must the bar of rationalism be set?

We should be careful in labelling ourselves as "rationalists" rather than just thinking rationally, for even the very wise cannot see all ends.
