I am currently pursuing PhD in CS from the U.K. I have been seriously considering taking 3-4 months off from my PhD to study philosophy and psychology. Since PhD programme in the U.K is only 3 years, I find it hard to study these subjects along with doing my research. There have been several instances that have made me felt that I lack deeper thinking of concepts, and I very much would like to do have a framework to think about the world around me. Thus, I had been thinking to take a gap and read some books on it or take some courses at my university. If I do that, I will need to be off from my scholarship for that period of time. Are there such grants for science PhDs to read philosophy/pscyhology for 3-4 months?
