Let’s first turn to the question of objectivity: How objective is our perception in reality? A statement is objective if it is neutral and not influenced by prejudices, feelings and interests. An objective statement is consequently independent of the person who makes this statement. The objective statement corresponds with the facts. We often tend to view our own perception of things or events as objectively correct. What others think of the same events or things we frequently categorize as incorrect or subjective (perceptive reality).
A good example is the weather: Two weeks of sunshine, high temperatures and no rain for many people is seen as desirable and good. The farmer however would like some rain in between times because otherwise his fields dry out, older people are not so happy with high air temperatures because it causes breathing difficulties etc. Who is being objective here? Obviously our assessment of the weather depends amongst other things significantly on what we want to do (swimming in an outdoor pool, working in the field, working in an office, travelling, resting etc.), upon our mood and our state of health. Exactly the same weather on a given day gives one person great pleasure and another one annoyance. But even within ourselves the assessment depends strongly on our plans: If we are working in an office three successive days of rain normally would not bother us too much. If however we are on a beach holiday we would want other weather!
