We have dealt so far with the achievement of Dr Lisboa as a scientist, but his work as a patriot is not less important. In all his actions, his noblest motive, to use the words of Virgil, was the ‘public good.’ Often his views on communal subjects were far in advance of his time, and consequently his advice did not meet with that respect and response which it otherwise so rightly deserved. Thus, presiding over the meeting which had been convened to build a national church for the Bombay and Goans, Dr Lisboa strongly urged his generation to content itself only with the task of securing an extensive plot centrally situated and to leave the building of a cathedral worthy of the community to the next generation. The advice was not heeded to, and we know the disastrous consequences and that too, of a permanent nature. He took a living interest in all the affairs of the community, in the management of the Instituto Luso-Indiano under whose auspices he spoke more than once. He defended the Padroado. He achieved great heights in his life.
