I remember posting a similar topic in the past, which eventually got locked lol. So, I'll go ahead and copy/paste what I have said in regards to the meaning behind my username.
For me, it all started in community college when I was taking an introductory philosophy course as a computer science major. I was learning about John Locke and René Descartes, and a concept was brought up about “moral truth.” This really opened my mind and changed my perspective on life. This got me thinking about a lot of things. Is there a true way of morality? Are morals subjective? Is there a way we’re supposed to go through in life that best affects the people around us in a positive way? Several more questions besides these came to mind, and then it hit me to use “Moral Truth” as my username. I wanted to have a name that has meaning and can be resonated with myself and others. Seeing that phrase as my name is a daily reminder for me to walk the path of goodness and positivity. Later on, I finally changed my major to philosophy, graduated from community college, and I’m currently pursuing philosophy as my major in university. I love learning about life’s different concepts/ideas from different perspectives, as well as learning how to construct/analyze arguments properly. Philosophy does require to have an open mind, and that’s what I’ve learned to do. :)
