Socrates says in The Phaedo that “People who apply themselves in the right way to philosophy are preparing for death. This passage for me was a little weird first because in a way it can be very similar of how I think.
Socrates is explaining to Simmias and Cebes, hos it seems natural that a man who has really devoted his life to philosophy should be cheerful that life is finished in other words how can someone be happy about death. So even when the main topic here is death I want to talk a little bit of what we supposed to do with our time on earth. We know that philosophy means the study of the fundamental nature of knowledge, reality, and existence so if we live base on this we are going to understand and archive knowledge. If we do all this we are applying ourselves in philosophy and we are preparing for death because we are learning for our next life. Socrates suggests or believes that we need to prepare our souls and minds to our next life.
This claim was not a challenge for me because in some way I believe in life after this one. I believe that we need to educate ourselves and we need to live in peace with everyone because your next life will be according of how you lived this one.
