Although Hadewijch discusses the relationship between love and reason throughout many of her works, her perception of the relationship seems to change over time. She begins by seeing reason as a tool which must be used with caution. Later she refines this view, showing reason as a tool which must be used to fully experience love.
In her 4th Letter, Role of Reason, Hadewijch outlines the areas where she feels men err in reason because they do not properly understand or practice hope, charity, rule of life, tears, desire of devotion, bent for sweetness, terror of God’s threats, distinction between beings, receiving, giving, etc (53). She outlines each of these points in depth, with the ultimate conclusion that man’s reason errs when it attempts to obey anything that does “not belong to perfect love” (55). But she feels that we can use reason to “[throw] light on each of these points according to their value” (55). This marks a common tension in her works, that of the obedient servant to that of the questioning but loyal one.
Hadewijch’s 30th Poem, Love and Reason, depicts a spiritual journey in which Love and Reason are personified. She has a relationship first with just Love, which when fully realized, “was wanting” and “gave [her] pain” (213). She then seeks “Reason’s counsel about Love,” only to realize that a purely rational examination of Love removes “the attire Lover herself had given” her (214). She finally comes to the conclusion that “one can win / veritable fruition of Love” through Reason, which allows one to fulfill the desires of both Love and Reason. The ultimate conclusion of this poem is that although it is a tough and painful journey, one cannot become spiritually complete without first justifying one’s love with one’s reason. This theme is also continued in some of her other work.
The 9th Vision of Hadewijch, Queen Reason, yet again personifies reason, this time as a regal queen wearing a dress composed of the “knowledge of love” (286). In this vision, she sees Reason accompanied by three maidens, who she later identifies as her Holy Fear, Discernment between Reason and Love, and Wisdom. She sees the queen at first as an ominous threat, but soon overcomes her fear. After reflecting truly on her beliefs, she deposes reason from her rank as queen to that of subject. Only after this, does the once again personified Love come and embrace her. Once again, we are shown her need to overcome reason in order to have a full relationship with Love.
For Hadewijch, reason is a necessity; albeit an unpleasant one. She feels that reason is a tool with which one can examine oneself from a spiritual perspective. The three maidens identified in her vision are the best way of defining the role of reason for her: allowing her to see in what ways she is completely adhering to her relationship with God, to identify what matters belong to the spiritual realm and what to the physical, and finally grant her wisdom in a sense similar to that of Bernard of Clairvaux, the knowledge of God as God, and being able to see oneself as God does. Without these tools, ones might feign a relationship with God, but will never attain the level of faith possible by first overcoming reason.
