The Scientific Method Quotes

The scientific method strips away guesswork, revealing truth through relentless curiosity and disciplined doubt—where every hypothesis is a test and every experiment a step toward clarity. These quotes capture its rigor, its humility, and the quiet thrill of uncovering what was always there, waiting to be seen.

“To satisfy our doubts . . . it is necessary that a method should be found by which our beliefs may be determined by nothing human, but by some external permanency -- by something upon which our thinking has no effect. . . . Our external permanency would not be external, in our sense, if it was restricted in its influence to one individual. It must be something which affects, or might affect, every man. And, though these affections are necessarily as various as are individual conditions, yet the method must be such that the ultimate conclusion of every man shall be the same. Such is the method of science. Its fundamental hypothesis, restated in more familiar language, is this: There are Real things, whose characters are entirely independent of our opinions about them; those Reals affect our senses according to regular laws, and, though our sensations are as different as are our relations to the objects, yet, by taking advantage of the laws of perception, we can ascertain by reasoning how things really and truly are; and any man, if he have sufficient experience and he reason enough about it, will be led to the one True conclusion. The new conception here involved is that of Reality. It may be asked how I know that there are any Reals. If this hypothesis is the sole support of my method of inquiry, my method of inquiry must not be used to support my hypothesis. The reply is this: 1. If investigation cannot be regarded as proving that there are Real things, it at least does not lead to a contrary conclusion; but the method and the conception on which it is based remain ever in harmony. No doubts of the method, therefore, necessarily arise from its practice, as is the case with all the others. 2. The feeling which gives rise to any method of fixing belief is a dissatisfaction at two repugnant propositions. But here already is a vague concession that there is some one thing which a proposition should represent. Nobody, therefore, can really doubt that there are Reals, for, if he did, doubt would not be a source of dissatisfaction. The hypothesis, therefore, is one which every mind admits. So that the social impulse does not cause men to doubt it. 3. Everybody uses the scientific method about a great many things, and only ceases to use it when he does not know how to apply it. 4. Experience of the method has not led us to doubt it, but, on the contrary, scientific investigation has had the most wonderful triumphs in the way of settling opinion. These afford the explanation of my not doubting the method or the hypothesis which it supposes; and not having any doubt, nor believing that anybody else whom I could influence has, it would be the merest babble for me to say more about it. If there be anybody with a living doubt upon the subject, let him consider it.”

Charles Sanders Peirce

“One reader of an early draft of this chapter complained at this point, saying that by treating the hypothesis of God as just one more scientific hypothesis, to be evaluated by the standards of science in particular and rational thought in general, Dawkins and I are ignoring the very widespread claim by believers in God that their faith is quite beyond reason, not a matter to which such mundane methods of testing applies. It is not just unsympathetic, he claimed, but strictly unwarranted for me simply to assume that the scientific method continues to apply with full force in this domain of truth.Very well, let's consider the objection. I doubt that the defender of religion will find it attractive, once we explore it carefully.The philosopher Ronaldo de Souza once memorably described philosophical theology as "intellectual tennis without a net," and I readily allow that I have indeed been assuming without comment or question up to now that the net of rational judgement was up. But we can lower it if you really want to.It's your serve.Whatever you serve, suppose I return service rudely as follows: "What you say implies that God is a ham sandwich wrapped in tin foil. That's not much of a God to worship!". If you then volley back, demanding to know how I can logically justify my claim that your serve has such a preposterous implication, I will reply: "oh, do you want the net up for my returns, but not for your serves?Either way the net stays up, or it stays down. If the net is down there are no rules and anybody can say anything, a mug's game if there ever was one. I have been giving you the benefit of the assumption that you would not waste your own time or mine by playing with the net down.”

Daniel C. Dennett

“Our conduct of the ontological investigation in the first and second parts opens up for us at the same time a view of the way in which these phenomenological investigations proceed. This raises the question of the character of method in ontology. Thus we come to the third part of the course: the scientific method of ontology and the idea of phenomenology. The method of ontology, that is, of philosophy in general, is distinguished by the fact that ontology has nothing in common with any method of any of the other sciences, all of which as positive sciences deal with beings. On the other hand, it is precisely the analysis of the truth-character of Being which shows that Being also is, as it were, based in a being, namely, in the Dasein. Being is given only if the understanding of Being, hence the Dasein, exists. This being accordingly lays claim to a distinctive priority in ontological inquiry. It makes itself manifest in all discussions of the basic problems of ontology and above all in the fundamental question of the meaning of Being in general. The elaboration of this question and its answer requires a general analytic of the Dasein. Ontology has for its fundamental discipline the analytic of the Dasein. This implies at the same time that ontology cannot be established in a purely ontological manner. Its possibility is referred back to a being, that is, to something ontical―the Dasein. Ontology has an ontical foundation, a fact which is manifest over and over again in the history of philosophy down to the present. For example, it is expressed as early as Aristotle's dictum that the first science, the science of Being, is theology. As the work of the freedom of the human Dasein, the possibilities and destinies of philosophy are bound up with man's existence, and thus with temporality and with historicality, and indeed in a more original sense than is any other science. Consequently, in clarifying the scientific character of ontology, *the first task is the demonstration of its ontical foundation* and the characterisation of this foundation itself."―from_The Basic Problems of Phenomenology_”
