Free thought can explore anywhere the mind can think to go, and there is an infinity of thoughts that can be brought into being with a sufficiently pointed vocabulary to express those thoughts. That leads to free speech with its ability to bring those thoughts into the external world outside of one’s own mind and that permits other people, and these days even some advanced computer minds, to understand those thoughts. Thus, there is presently a vast number of minds, some seven billion human minds and a handful of computer minds at present, to explore the infinity of possible thoughts. With that exploration comes the possibility that some of the thoughts can be applied to testable reality. With that opportunity comes the necessity for free action to permit the discovery of things which are beneficial to the categories of beings that we value and hold dear.
With those freedoms then comes the necessity of exposing into existence via speech and action those ideas that are helpful and also exposing those that are hurtful. When we identify those ideas that are hurtful when coupled with free speech and free action, it becomes our obligation to use our free thought coupled with our free speech and our free action to take those that are destructive and eliminate them.
Each of the freedoms of thought, speech, and action, both helpful and unhelpful, must be identified by us as individuals and confronted publicly.
