Rationality without empiricism is impossible. A child born without experience is not considered “alive” for a reason. (This may sound circular but) we necessarily start with reality, then experience, then thought (reason). What ends in death is experience and thought but not reality, for the body remains.
This may be a common sense view, a conventional view, a “reductive” point-of-view but there is nothing that I should apologise for … except for being boring perhaps.
