Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.
You never stopped thinking of yourself as a writer biding his time in the Department of Factual Verification. But between the job and the life there wasn't much time left over for emotion recollected in tranquillity.
From this we conclude, that, to live in harmony and peace... we must trace a line of distinction between those (assertions) that are capable of verification, and those that are not; (we must) separate by an inviolable barrier the world of fantastical beings from the world of realities.
What's your favorite book?' is a question that is usually only asked by children and banking identity-verification services-and favorite isn't, anyway, the right word to describe the relationship a reader has with a particularly cherished book. Most serious readers can point to one book that has a place in their life like the one that 'Middlemarch' has in mine.
Any chemist reading this book can see, in some detail, how I have spent most of my mature life. They can become familiar with the quality of my mind and imagination. They can make judgements about my research abilities. They can tell how well I have documented my claims of experimental results. Any scientist can redo my experiments to see if they still work-and this has happened! I know of no other field in which contributions to world culture are so clearly on exhibit, so cumulative, and so subject to verification.
One of the bigger mistakes of our time, I suppose, was preaching the demonization of all judgment without teaching how to judge righteously. We now live in an age where, apart from the inability to bear even good judgment when it so passes by, still everyone, inevitably, has a viral opinion (judgment) about everything and everyone, but little skill in good judgment as its verification or harness.
Praxeology is a theoretical and systematic, not a historical, science. Its scope is human action as such, irrespective of all environmental, accidental, and individual circumstances of the concrete acts. Its cognition is purely formal and general without reference to the material content and the particular features of the actual case. It aims at knowledge valid for all instances in which the conditions exactly correspond to those implied in its assumptions and inferences. Its statements and propositions are not derived from experience. They are, like those of logic and mathematics, a priori. They are not subject to verification or falsification on the ground of experience and facts.
It is obvious that the concept of truth has become suspect. Of course it is correct that is has been much abused. Intolerance and cruelty have occurred in the name of truth. To that extent people are afraid when someone says, "This is the truth", or even "I have the truth". We never have it, at best is has us. No one will dispute that one must be careful and cautious in claiming the truth. But simply to dismiss it as unattainable is really destructive. (...) We must have the courage to dare to say: Yes, man must seek the truth; he is capable of truth. It goes without saying that truth requires criteria for verification and falsification. It must always be accompanied by tolerance, also. But then truth also points out to us those constant values which have made mankind great. That is why the humility to recognize the truth and to accept it as a standard has to be relearned and practiced again. The truth comes to rule, not through violence, but rather through its own power; this is the central theme of John's Gospel: When brought before Pilate, Jesus professes that he himself is The Truth and the witness to the truth. He does not defend the truth with legions but rather makes it visible through his Passion and thereby also implements it.
