The circumstances of life could not determine the way someone thinks. Only the thinker can let them to enter in his thought.
He can invite them as objects of his thought and then his thought becomes sheer description of various facts.
Or he can let his thought to grasp the things through the circular pattern of circumstances and borrowing the flowing character of life.
In this last case, whenever a thought is judged according to the biographical records of its author, there is easily committed the confusion between the ‘mine’ of his thought and the ‘mine’ of his life.
Thought belongs to someone anytime, therefore, it can be recognized such ‘mine’, but life circumstances that are assimilated by thought loose their personal character.
