Under some circumstances, I recognize fear as an ally that serves to alert me to possible danger. One example is the stormy night when the temperature makes roads icy. Fear of sliding off the road and into a ditch is a good thing because it may prevent me from driving under dangerous conditions. If I see a vicious dog tied to a tree, fear keeps me from petting it. Logical fear is a useful deterrent, which keeps me from putting myself in harm’s way.
