“By asserting the objectivity of the physical world, natuaralism identifies the existence and the conditions of existence of the physical world with existence and the conditions of existence in general. It forgets that the world of the physicist necessarily refers back, through its intrinsic meaning, through the subjective world which one tries to exclude from reality as being pure appearance, conditioned by the empirical nature of man, which is incapable of reaching directly to a world of things in themselves. But while the world of the physicist claims to go beyond naive experience, his world really exists only in relation to naive experience.”

Context: World is the pattern of meaningful relations in which a person exists and in the design of which he or she participates. It has objective reality, to be sure, but it is not simply that. World is interrelated with the person at every moment. A continual dialectical process goes on between world and self and self and world; one implies the other, and neither can be understood if we omit the other. This is why one can never localize creativity as a subjective phenomenon; one can never study it simply in terms of what goes on within the person. The pole of world is an inseparable part of the creativity of an individual. What occurs is always a process, a doing — specifically a process interrelating the person and his or her world.

Context: It is not the laws of physics that make science possible but the unprovable proposition that there exists a grand design underlying the physical world. And not just any old "grand design" but one that is accessible to the limited senses and modest reasoning powers of the species to which we belong. Scientists subscribe with such conviction to this article of faith that they are willing to commit a lifetime to the pursuit of scientific discovery. It is hardly surprising that an activity so magical is also undefinable. Science is what scientists do. And what they do is look around themselves for messages written in the sky, the earth, the oceans and all living things – messages that tell of the unity of creation. These messages have been there – unseen, though at times written in letters miles high – since the dawn of history. But we have just passed through an epoch in which, quite suddenly, scientists seem to have learnt speed reading. Discoveries have been coming at an unprecedented pace. In the wake of such a period it is common to consider that we may be approaching the point where all that is readable in nature will have been read. We should be skeptical of such claims. Success in reading some messages brings with it a temporary blindness to others. We forget that between the words written in black in nature's book there are likely to be messages of equal importance written in white. It is a truism that success in science comes to the individuals who ask the right questions.

Mind and Matter (1958), p. 127
Context: The world is given to me only once, not one existing and one perceived. Subject and object are only one. The barrier between them cannot be said to have broken down as a result of recent experience in the physical sciences, for this barrier does not exist.
