Helena Petrovna Blavatsky
“We may not be in sympathy with materialism, and may even abhor it; yet the Theosophical Society ought never to forget that which it owes to Freethinkers. It is to the unceasing efforts of a long series of adherents to Freethought— almost every one of whom has been made a martyr to his convictions at the hands of bigotry—that we, in the present century owe the very possibility of our existence as an organized body.” Lucifer, 1889, volume 5, n. 25, page 76. Suppressio Veri Suggestio Falsi, by the Adversay (HPB).
“LUCIFER—the spirit of Intellectual Enlightenment and Freedom of Thought—is metaphorically the guiding beacon, which helps man to find his way through the rocks and sandbanks of Life, for Lucifer is the LOGOS in his highest, and the “Adversary” in his lowest aspect—both of which are reflected in our Ego” The Secret Doctrine, Volume II, Stanza VII The Semi-Divine Down to the First Humanity page 162.
“The “lofty platform” is very flattering, though our modesty urges us to regard it as a mirage developed within the limitless area of our kind “friends and admirers’ “fancy. But, supposing it had any independent existence of its own, we would far rather descend from and abandon it forever, than accept the passive role of a dumb old idol, alike indifferent to the happiness as to the misery and woes of the surrounding world. We decline the exalted position if we have to secure it at the price of our freedom of thought and speech. Collected Writings volume 4 “The Chosen “Vessels of Election” Blavatsky
Valuing freedom of thought above all things, as the only way of reaching at some future time that Wisdom, of which every Theosophist ought to be enamoured, we recognize the right to the same freedom in our foes as in our friends. The Dual Aspect of Wisdom, H.P. Blavatsky. Lucifer, 1890, v. vii, n. xxxvii, pp. 1-9.
I need hardly point out how the proposed arrangement is calculated to lead to a harmonious progress of the “L.L.T.S.” It is a universally admitted fact that the marvellous success of the Theosophical Society in India is due entirely to its principle of wise and respectful toleration of each other’s opinions and beliefs. Not even the President-Founder has the right directly or indirectly to interfere with the freedom of thought of the humblest member, least of all to seek to influence his personal opinion. It is only in the absence of this generous consideration, that even the faintest shadow of difference arms seekers after the same truth, otherwise earnest and sincere, with the scorpion-whip of hatred against their brothers, equally sincere and earnest. Deluded victims of distorted truth, they forget, or never knew, that discord is the harmony of the Universe.
