Philosophy of Science
There is no such thing as a soul, or a seperate ‘mind’ outside our brains and body. We are infact no more than the chemicals, atoms, and neurons that make us up, our conscious, our thoughts, these derive from our biological organisation. So defining a person can be problematic, surely if I take a paracetamol I am no longer the same person as I was a few minutes ago before I took it, because, ultimately my biology has changed since then. Furthermore without paracetamol or infact any kind of drug my biology changes constantly anyway, so my persistence as appearing as the same person is not as a result of me being the same person but as a result of people percieving me as the same person. Personhood is no more than an illusion, we are not people, we are just collections of atoms, and these atoms and our cells are changing all the time, we are changing all the time. Following this there is no objective explanation of what makes a person, because really a person is never in existence as that person for any length of time at all, in just a few minutes an element within me will have changed. Infact time can become an issue, time is infinite, it can always be smaller. So detecting when a change occurs is impossible, most people would accept that I am not the same person I was 10 years ago, but when exactly did I change? It’s impossible to know because there is always a smaller millisecond in existence so a better way to judge is when others begin to identify me as different. My only true claim to being a continuous person is a series of successful and similar actions I do that lead others to percieve me to be the same, I am not the same, but being perceived as the same is what defines me as a person, really the idea of a person is not more than an illusion. This idea of personhood and how it’s percieve relies on a holistic view, I am judged and I judge others holositically, I don’t scrutinise their individual elements but focus on them as a whole and so this almost vague attention to detail when it comes to percieving others allows for generalisation of the indictable components to be seen as the same, thus ignoring minute changes within biology.
