Hindi mapalagay (en. Implacable)

Translation into Tagalog

But he also was the victim, as he himself recognised, of an uncontrollable temper; and his devotion to scientific truth as he saw it being literally passionate, he was an implacable enemy of those whom he judged guilty of propagating error.

Ngunit siya rin ay ang mga biktima, bilang niya ang sarili na kinikilala, hindi mapipigil ng isang kainitan ng ulo; at ang kanyang debosyon sa pang-agham na katotohanan na niya nakita ito na literal mapusok, siya ay isang mapayapa kaaway ng mga sinugo siya hinahatulan may kasalanan ng propagating error.
