Our time strives for intelligence and logic, but those who want to be at the head of the scientific or cultural efforts of our time do not possess a lot of keen mind and logic.
One does not aim at the whole clearness of thinking in our time at all. If one fully aimed at the clearness of thinking, one would also be able to understand spiritual science completely. Who thinks clearly cannot argue anything against that which spiritual science has to bring forward — of course on the whole; since the spiritual scientist can be mistaken as the human being can generally be mistaken. Countless examples could be given which show us that just our time is little inclined to apply clear, keen thinking.
