time is an arbitrary construct based on positions of celestial objects. there is no past and no future, only an ever-expanding moment in the present. if we can remember and if we can plan - our present moment is more expansive. destruction of memories (thru alzheimer's and other types of dementia) and hope (thru inflation) leads to a shrunken present moment.
knowledge and science are a noble pursuit, as opposed to not-knowing and nescience. the goal is con-science (knowing together).
liberty is acquired by reading from a library of knowledge, from the word liber, book. i.e. knowledge is acquired thru liberty, and that's how we become free in our own kingdom, freedom. no liberty - no freedom.
