In contrast to the subjectivism of the conscious mind the unconscious is objective, manifesting itself mainly in the form of contrary feelings, fantasies, emotions, impulses and dreams, none of which one makes oneself but which come upon one objectively.

What we call objective reality is, in the last analysis, what is common to many thinking beings, and could be common to all; this common part, we shall see, can only be the harmony expressed by mathematical laws. It is this harmony... which is the sole objective reality, the only truth we can attain; and when I add that the universal harmony of the world is the source of all beauty, it will be understood what price we should attach to the slow and difficult progress which little by little enables us to know it better.

The problem is one of opposition between subjective and objective points of view. There is a tendency to seek an objective account of everything before admitting its reality. But often what appears to a more subjective point of view cannot be accounted for in this way. So either the objective conception of the world is incomplete, or the subjective involves illusions that should be rejected.

[W]hen the objective gaze is turned on human beings and other experiencing creatures, who are undeniably parts of the world, it can reveal only what they are like in themselves. And if the way things are for these subjects is not part of the way things are in themselves, an objective account, whatever it shows, will omit something. So reality is not just objective reality, and the pursuit of objectivity is not an equally effective method of reaching the truth about everything.

The world of our experience consists at all times of two parts, an objective and a subjective part, of which the former may be incalculably more extensive than the latter, and yet the latter can never be omitted or suppressed. The objective part is the sum total of whatsoever at any given time we may be thinking of, the subjective part is the inner "state" in which the thinking comes to pass.

Comprehension is neither an arbitrary act nor a passive experience, but a responsible act claiming universal validity. Such knowing is indeed objective in the sense of establishing contact with a hidden reality; a contact that is defined as the condition for anticipating an indeterminate range of yet unknown (and perhaps yet inconceivable) true implications. It seems reasonable to describe this fusion of the personal and the objective as Personal Knowledge. Personal knowledge is an intellectual commitment, and as such inherently hazardous. Only affirmations that could be false can be said to convey objective knowledge of this kind.

It is when subjective consciousness maintains its independence of everything, that it says, 'It is I who through my educated thoughts can annul all determinations of right, morality, good, &c., because I am clearly master of them, and I know that if anything seems good to me I can easily subvert it, because things are only true to me in so far as they please me now.' This irony is thus only a trifling with everything, and it can transform all things into show: to this subjectivity nothing is any longer serious, for any seriousness which it has, immediately becomes dissipated again in jokes, and all noble or divine truth vanishes away or becomes mere triviality.

Objectivity is a subject's delusion that observing can be done without him. Involving objectivity is abrogating responsibility – hence its popularity.

The sum of the knowable, that soil which the human spirit must till, lies between all the languages and independent of them, at their center. But man cannot approach this purely objective realm other than through his own modes of cognition and feeling, in other words: subjectively. Just where study and research touch the highest and deepest point, just there does the mechanical, logical use of reason - whatever in us can most easily be separated from our uniqueness as individual human beings - find itself at the end of its rope. From here on we need a process of inner perception and creation. And all that we can plainly know about this is its result, namely, that objective truth always rises from the entire energy of subjective individuality.

There is no objective reality. But there is only an illusion of consciousness, there is only an objectivication of reality, which was created by the spirit. The origin of life is creativity, freedom; and the personality, subject, and spirit are the representatives of that origin, but not the nature, not the object.

I consider those developments in physics during the last decades which have shown how problematical such concepts as "objective" and "subjective" are, a great liberation of thought. The whole thing started with the theory of relativity. In the past, the statement that two events are simultaneous was considered an objective assertion, one that could be communicated quite simply and that was open to verification by any observer. Today we know that 'simultaneity' contains a subjective element, inasmuch as two events that appear simultaneous to an observer at rest are not necessarily simultaneous to an observer in motion. However, the relativistic description is also objective inasmuch as every observer can deduce by calculation what the other observer will perceive or has perceived. For all that, we have come a long way from the classical ideal of objective descriptions. In quantum mechanics the departure from this ideal has been even more radical. We can still use the objectifying language of classical physics to make statements about observable facts. For instance, we can say that a photographic plate has been blackened, or that cloud droplets have formed. But we can say nothing about the atoms themselves. And what predictions we base on such findings depend on the way we pose our experimental question, and here the observer has freedom of choice. Naturally, it still makes no difference whether the observer is a man, an animal, or a piece of apparatus, but it is no longer possible to make predictions without reference to the observer or the means of observation. To that extent, every physical process may be said to have objective and subjective features. The objective world of nineteenth-century science was, as we know today, an ideal, limiting case, but not the whole reality. Admittedly, even in our future encounters with reality we shall have to distinguish between the objective and the subjective side, to make a division between the two. But the location of the separation may depend on the way things are looked at; to a certain extent it can be chosen at will. Hence I can quite understand why we cannot speak about the content of religion in an objectifying language. The fact that different religions try to express this content in quite distinct spiritual forms is no real objection. Perhaps we ought to look upon these different forms as complementary descriptions which, though they exclude one another, are needed to convey the rich possibilities flowing from man's relationship with the central order.

We humans like to imagine that we have an objective knowledge of the world. We take it for granted that what we perceive on a daily basis is reality—this reality being more or less the same for everybody. But this is an illusion. No two people see or experience the world in the same way. What we perceive is our personal version of reality, one that is of our own creation. To realize this is a critical step in our understanding of human nature.

Subjective conscious mind is an analog of what is called the real world. It is built up with a vocabulary or lexical field whose terms are all metaphors or analogs of behavior in the physical world. Its reality is of the same order as mathematics. It allows us to shortcut behavioral processes and arrive at more adequate decisions. Like mathematics, it is an operator rather than a thing or repository. And it is intimately bound up with volition and decision.
