He worked in several fields like many "scientists" did back in those times. He was not merely a philosopher or a writer but also a statesman, anatomist, botanist and physicist.

We become too absorbed into our professional identities of being a programmer or biologist or engineer and tend to forget that we are of course more than just our job and have freedom to invest our intellectual rigour into anything and everything.
