While it is truly sad that Philip has left this world before his time, we can all take solace in the fact that while he was here he made an impact on humanity that will far surpass what most of us can do, and left us with a wealth of his wisdom and experience that we can draw on to improve ourselves for the future.
His impact on "us" cannot be denied, and we shall use that influence to better ourselves in times to come. Our sadness for his passing should not be outweighed by our appreciation of his life and what he was able to accomplish in the time that he did have.
