The word objective is almost sacred to the scientist.  Every student should know its meaning.  The antonym for objective is subjective, which means personal.  The subjective world lies within oneself and includes one's feelings, desires, wishes, hopes, longings--one's whole private world, which is quite incommunicable to others.  On the other hand, objective means that attention is centered ont he object outside of the observing mind.  When we think objectively, our whole interest lies in the object that we wish to describe, measure, and observe as an entity in and of itself.  We try to set aside all likes and dislikes, all prejudices, all emotional coloring to behold the object "in the white light of objectivity."
