Phaedrus's Blade.  First, a well-trained and clear uncluttered mind. In the university, use of this weapon is taught in the courses dealing with Logic and Reasoning. It is the principal weapon which one uses in philosophy. This is the technical side of being a Knight. You must learn to use your mind to cut concepts up into every size and shape imaginable. The sharpness of your Blade is the sharpness of your mind. The Blade is thus a metaphor for mental agility.

      Magnus's Shield. Second. Now philosophers have always been thin-skinned. How else can they maintain the sense of wonder that keeps them wondering? Being so thin-skinned requires some protection from the elements, namely spittle from the mouths of 'illuminated' philistines.

      Godly Plate of Light. Now being armed and shielded is not enough. Philosophers wander around in such blind confusion that they always bump into hard objects, or otherwise things happen to them that they never see coming in their search for truth. To protect yourself ( and your shins ;D ), you MUST have body armour. Otherwise you suffer the consequences. Be warned ~! A close substitute is maturity or experience.

      The Razor The Other Weapon. The Razor has more to do with intuition, with creativity, with wisdom, the slower ways of getting at truth. While Phaedrus's Blade represents the intellectual sharpness of the knight ( the better you have mastered the use of it, the sharper your mind ), it is the Razor that determines the skill with which he wields it. Using the Razor allows you to put back together again in a new way things that you have cut up with the Blade.

       The Razor is the most difficult item to master. Once mastered, you will tackle all problems using your intuition and creativity as your guide. Coupled with the mastery of the Blade and the protection of your armour and shield, you will then become a real Truth Knight.
