We humans are full of unpredictable emotions that logic alone cannot solve.

Men often succumb to their emotions when it requires them to use their logic. When it calls for them to rely on emotions, they turn to logic instead.

Emotions without logic are blind. Logic without emotions is dull. Logic with positive emotions leads to wise actions.

The emotional tail wags the rational dog.

Don't make the effort to appeal to logic and reasoning all the time; very few people can relate to that. Appeal to emotions instead; everyone, at least, can relate to that.

Of my friend, I can only say this: of all the souls I have encountered in my travels, his was the most... human.
