Part of an article is summarized that discusses Lorentzian matrices in
detail and refutes an argument by Galeczki in which he claimed an inc
onsistency in the kinematics of the special theory of relativity (KSTR
). He has recently published a new argument against KSTR, but this is
again fallacious, although his article certainly contains food for tho
ught regarding STR as such. Also, a reply is given to a question asked
by Phipps concerning a paper on the self-consistency of KSTR. Reasons
for ''doubting Thomas'' are presented.
