There are certain objects which may be known by any of the four methods, there are other objects which must be known by a particular method and cannot be known by any other. Like, the existence of fire at a distant place may be known from the testimony of a reliable person or it may also be known by inference from the observed smoke as a mark of fire. Or, if we take the trouble to go up to the place from which smoke issues forth, we have a perception of the fire on the spot. Hence with regard to such objects as the fire, one method of knowledge is as good and valid as any other. | There are certain objects which may be known by any of the four methods, there are other objects which must be known by a particular method and cannot be known by any other.
