: A surgeon.
I stab you and I cut you, yet I mean you no harm! What am I?
All have tried to catch me, none have kept me! What am I?
: A conscience.
What burdens without weight and guides without a destination?
To have one third you must give, without me not long you shall live! What am I?
: A keen mind.
I slow with the passage of time, yet I am quick without movement! What am I?
