Science is not built on trust but on objective verification.... Pure science concerns itself with investigation, not its product line. Poorly defined words, mysticism and emotional thoughts that are called arguments are common in aikido forums and dojos. This approach has been tried before and failed.
In-yo. Both have a place. Aikido is as much about the physics (big on the physics, myself) as it is about the affective elements. The latter drives people to do it in training, and to perform it properly in critical circumstances. Physics can't do that.
You cannot ignore the physics, but you cannot ignore the poetry, either, physical and otherwise.
