Rabbi Yochanan and Reish Lakish disagree regarding the nature of the reason for one's liability for damage caused by fire. Is the damage caused by the fire similar to a person shooting arrows or is it like damage caused by their property, i.e. the fire is seen as the property of the one who lit it and therefore similar to a person's ox or pit damaging? The Gemara attempts, unsuccessfully, to prove Rabbi Yochanan's approach - fire is like a person shooting an arrow.
