  In an earlier paper~\cite{Luu:2019jmb} we discussed emergence from the
context of effective field theories, particularly as related to the fields of
particle and nuclear physics. We argued on the side of reductionism and weak
emergence. George Ellis has critiqued our exposition in~\cite{Ellis:2020vij},
and here we provide our response to his critiques. Many of his critiques are
based on incorrect assumptions related to the formalism of effective field
theories and we attempt to correct these issues here. We also comment on other
statements made in his paper. Important to note is that our response is to his
critiques made in archive versions arXiv:2004.13591v1-5 [physics.hist-ph]. That
is, versions 1-5 of this archive post. Version 6 has similar content as
versions 1-5, but versions 7-9 are seemingly a different paper altogether (even
with a different title).
