The experimental universal is acquired by us, whose mind's eye is not purely spiritual, only through the help of the senses. For when the senses several times observe two singular occurrences, of which one is the cause of the other or is related to it in some other way, and they do not see the connection between them... And from this perception repeated again and again and stored in memory, and from the sensory knowledge from which the perception is built up, the functioning of the reasoning begins. The functioning reason therefore begins to wonder and to consider whether things really are as the sensible recollection says, and these two lead the reason to experiment... But when he has administered many times with the sure exclusion of all other things [that could be mistaken for the cause]... then there is formed in the reason this universal... and this is the way in which it comes from sensation to a universal experimental principle.

We will not be picking up axes and breaking into people's homes. But we will not remain silent either. Moderation in the face of evil is not what our age needs. As Ronald Reagan declared, "The future doesn't belong to the fainthearted." We must uncap our pens; we must speak words of truth. We are facing a determined enemy who is striving through all means to destroy the West and snuff out our traditions of free thought, free speech, and freedom of religion. Make no mistake: if we fail, we will be enslaved. We must not let the violent fanatics dictate what we draw, what we say, and what we read. We must rebel against their suffocating rules and thuggish demands at every turn. You can help the fight just by reading this book, which explains the many ways in which Islam has marked for death not just me, but all of Western civilization. We must, in the words of Revolutionary War veteran General John Stark, "Live free or die."

There is no necessary connection between the important events of a life and the records of it that have been preserved in memory, in documents, in memorials, or in living testimony. The biographer must compose his life of what he has, just as the archeologist must restore his temple or his statue with such fragments as thieving time and careless men have left him; but fate often ironically leaves him a well-preserved leg and a dismembered torso, while the head, which would supply the main clue to the body, is missing. Hence, in addition to the purposive selection exercised by the subject himself and by the biographer in making use of such materials as are left, there exists a purely external selection dominated by chance, which cuts across the evidence in an arbitrary fashion. To correct for such distortions the biographer must be an anatomist of character: he must be able to restore the missing nose in plaster, even if he does not find the original marble.
Lewis Mumford
An explanation of a phenomenon is regarded, apparently instinctively, as the most general possible when it is a mechanical explanation. The "mechanism" of the process is the ultimate goal of experiment. Now this mechanism in general lies beyond the range of the senses; either by reason of their limitations, as in the case of the atomic structure of matter, or by the very nature of the supposed mechanism, as in the theory of the ether. The only way to bridge the gap between the machinery of the physical process and the world of sense-impressions is to think out some consequence of that mechanism. This we will call the hypothesis. The hypothesis, resting still on the mechanical basis, is yet beyond the range of direct experimental investigation; but if, by mathematical reasoning, a consequence of the hypothesis can be deduced, this will often lie within the range of experimental inquiry, and thus a test of the soundness of the original mechanical conception may be instituted.
