“Dualism is the closest human feeling, but it is not necessarily the highest human philosophy. On the contrary, all great philosophies have been monistic. Man experiences the world dualistically, but monism is the essence of all human thinking. Philosophy disagrees with dualism. However, this fact does not mean too much, because life, being superior to thought, may not be judged by it. In reality, since we are human beings, we are living two realities. We can deny these two worlds, but we cannot escape from them. Life does not depend too much on our understanding of it.”

“Every human being relies on and is bounded by his knowledge and experience to live. This is what we call “reality”. However, knowledge and experience are ambiguous, thus reality can become illusion. Is it not possible to think that, all human beings are living in their assumptions?”

“for philosophy, Socrates, if pursued in moderation and at the proper age, is an elegant accomplishment, but too much philosophy is the ruin of human life.”

“Understanding the physiological and neurological features of spiritual experiences should not be interpreted as an attempt to discredit their reality or explain them away. Rather, it demonstrates their physical existence as a fundamental, shared part of human nature. Spiritual experiences cannot be considered irrational, since we have seen that, given their physiological basis, experiencers' descriptions of them are perfectly rational... All human perceptions of material reality can ultimately be documented as chemical reactions in our neurobiology; all our sensations, thoughts, and memories are ultimately reducible to chemistry, yet we feel no need to deny the existence of the material world; it is not less real because our perceptions of it are biologically based... It is not rational to assume that the spiritual reality of core experiences is any less real than the more scientifically documentable material reality.”

“Maybe each human being lives in a unique world, a private world different from those inhabited and experienced by all other humans. . . If reality differs from person to person, can we speak of reality singular, or shouldn't we really be talking about plural realities? And if there are plural realities, are some more true (more real) than others? What about the world of a schizophrenic? Maybe it's as real as our world. Maybe we cannot say that we are in touch with reality and he is not, but should instead say, His reality is so different from ours that he can't explain his to us, and we can't explain ours to him. The problem, then, is that if subjective worlds are experienced too differently, there occurs a breakdown in communication ... and there is the real illness.”

“My belief is that if we live another century or so — I am talking of the common life which is the real life and not of the little separate lives which we live as individuals — and have five hundred a year each of us and rooms of our own; if we have the habit of freedom and the courage to write exactly what we think; if we escape a little from the common sitting-room and see human beings not always in their relation to each other but in relation to reality; and the sky, too, and the trees or whatever it may be in themselves; if we look past Milton's bogey, for no human being should shut out the view; if we face the fact, for it is a fact, that there is no arm to cling to, but that we go alone and that our relation is to the world of reality and not only to the world of men and women, then the opportunity will come and the dead poet who was Shakespeare's sister will put on the body which she has so often laid down.”
