natural philosophy and natural rights are great instructors. one of the things i have learned is this. violence is not necessary. force in the use of self-defense is not always necessary but, should always, at least, be kept in reserve. violence is the uninitiated use of force. violence is force but, force need not be violence. natural philosophy is what physics used to be called. this is very instructive to me. it tells me, that, my personal philosophy will best function when it is not an invented construct just in my mind but, is a system based in observation and understanding of the natural world. thank you.
