“It is difficult to get a man to understand something, when his salary depends upon his not understanding it!” Upton Sinclair
You have to be curious enough and free enough to want to look.
You have to have the confront level adequate to observe what is there.
Not what you expect to be there.
Not what you want to be there.
Not what you are told that is there.
Not what the institution that pays your salary insists is there.
But the courage to see what is actually there.
Then you need to have the courage and integrity to act relative to what you observe is true.
