“In other words, the fundamental principles and indispensable postulates of every genuinely productive science are not based on pure logic but rather on the metaphysical hypothesis — which no rules of logic can refute — that there exists an outer world which is entirely independent of ourselves. It is only through the immediate dictate of our consciousness that we know that this world exists. And that consciousness may to a certain degree be called a special sense.”

“The fact that psychology postulates an external material world and studies it in so far as it comes to be reflected in consciousness, points to another postulate which psychology must assume in addition, namely, the existence of an inner world consciousness.”

“Under the conditions of modern life we have more control over our thoughts, and in connection with this there is a special method by which we may work on the development of our consciousness using that instrument which is most obedient to our will; that is, our mind, or the intellectual centre. In order to understand more clearly what I am going to say, you must try to remember that we have no control over our consciousness. When I said that we can become more conscious, or that a man can be made conscious for a moment simply by asking him if he is conscious or not, I used the words "conscious" or "consciousness" in a relative sense. There are so many degrees of consciousness and every higher degree means "consciousness" in relation to a lower degree. But, if we have no control over consciousness itself, we have a certain control over our thinking about consciousness, and we can construct our thinking in such a way as to bring consciousness. What I mean is that by giving to our thoughts the direction which they would have in a moment of consciousness, we can, in this way, induce consciousness.”

“I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness.”

“In immediate self-consciousness the simple ego is absolute object, which, however, is for us or in itself absolute mediation, and has as its essential moment substantial and solid independence. The dissolution of that simple unity is the result of the first experience; through this there is posited a pure self-consciousness, and a consciousness which is not purely for itself, but for another, i. e. as an existent consciousness, consciousness in the form and shape of thinghood. Both moments are essential, since, in the first instance, they are unlike and opposed, and their reflexion into unity has not yet come to light, they stand as two opposed forms or modes of consciousness. The one is independent whose essential nature is to be for itself, the other is dependent whose essence is life or existence for another. The former is the Master, or Lord, the latter is the Bondsman.”

“To say that there are certain fields—for example, metaphysics—from which science is excluded, wherein its methods have no application, is merely to say that the rules of methodical observation and the laws of logical thought do not apply to the facts, if any, which lie within such fields. These fields, if indeed such exist, must lie outside any intelligible definition which can be given of the word knowledge.”

“According to this view, the sentences of metaphysics are pseudo-sentences which on logical analysis are proved to be either empty phrases or phrases which violate the rules of syntax. Of the so-called philosophical problems, the only questions which have any meaning are those of the logic of science. To share this view is to substitute logical syntax for philosophy.”

“The viewpoint of the formalist must lead to the conviction that if other symbolic formulas should be substituted for the ones that now represent the fundamental mathematical relations and the mathematical-logical laws, the absence of the sensation of delight, called "consciousness of legitimacy," which might be the result of such substitution would not in the least invalidate its mathematical exactness. To the philosopher or to the anthropologist, but not to the mathematician, belongs the task of investigating why certain systems of symbolic logic rather than others may be effectively projected upon nature. Not to the mathematician, but to the psychologist, belongs the task of explaining why we believe in certain systems of symbolic logic and not in others, in particular why we are averse to the so-called contradictory systems in which the negative as well as the positive of certain propositions are valid.”

“Every animal possesses something which distinguishes it from all other animals; and this is what I understand by personal identity, or rather the identical self. This in every animal is perfectly distinct and indivisible, since the only knowledge we have of it is when it is entire; and divisibility of this is what we cannot conceive: but if indivisible, it must also be indestructible, and must always have existed. Itis not possessed of any kind of consciousness: but no consciousness can, it appears, exist without it; as life itself seems to be composed of personal identity, and other essentials of the mind or body, and that it is the combination which produces consciousness.”

“The functional validity of a working hypothesis is not a priori certain, because often it is initially based on intuition. However, logical deductions from such a hypothesis provide expectations (so called prognoses) as to the circumstances under which certain phenomena will appear in nature. Such a postulate or working hypothesis can then be substantiated by additional observations or by experiments especially arranged to test details. The value of the hypothesis is strengthened if the observed facts fit the expectation within the limits of permissible error.”

“All thought of something is at the same time self-consciousness […] At the root of all our experiences and all our reflections, we find […] a being which immediately recognises itself, […] and which knows its own existence, not by observation and as a given fact, nor by inference from any idea of itself, but through direct contact with that existence. Self-consciousness is the very being of mind in action.”
