“Don't accuse anyone with the temerity to question your sad supernatural fantasies of having a 'closed mind' or being 'blind to possibilities'. A closed mind asks no questions, unthinkingly accepting that which it wants to believe. The blindness is all yours.”

Context: So you must ask this question, put this question to yourself, whether your mind can be empty of all its past and yet retain the technological knowledge, your engineering knowledge, your linguistic knowledge, the memory of all that, and yet function from a mind that is completely empty. The emptying of that mind comes about naturally, sweetly without bidding, when you understand yourself, when you understand what you are. What you are is the memory, bundle of memories, experiences, thoughts. When you understand that, look at it, observe it; and when you observe it, see in that observation that there is no duality between the observer and the observed; then when you see that, you will see that your mind can be completely empty, attentive, and in that attention you can act wholly, without any fragmentation.

The Ethics of Belief (1877), The Weight Of Authority
Context: In regard, then, to the sacred tradition of humanity, we learn that it consists, not in propositions or statements which are to be accepted and believed on the authority of the tradition, but in questions rightly asked, in conceptions which enable us to ask further questions, and in methods of answering questions. The value of all these things depends on their being tested day by day. The very sacredness of the precious deposit imposes upon us the duty and the responsibility of testing it, of purifying and enlarging it to the utmost of our power. He who makes use of its results to stifle his own doubts, or to hamper the inquiry of others, is guilty of a sacrilege which centuries shall never be able to blot out. When the labours and questionings of honest and brave men shall have built up the fabric of known truth to a glory which we in this generation can neither hope for nor imagine, in that pure and holy temple he shall have no part nor lot, but his name and his works shall be cast out into the darkness of oblivion for ever.
