"Its not like you just have any old hallucination, youll have a visualisation of exactly what the ritual is set up to provide, so if you summon the Greek god Hermes you will see the Greek god Hermes. But I began to get different ideas about what these things really were and I was more interested in the effect rather than the explanation because I didnt believe in gods or devils or demons, but I knew that there was something - these were like mechanisms, these rituals that could trigger states of mind."
"However the development proceeds in detail, the path so far traced by the quantum theory indicates that an understanding of those still unclarified features of atomic physics can only be acquired by foregoing visualization and objectification to an extent greater than that customary hitherto..."
"The medium of printed scientific text is first of all a visual one."
"If statistical graphics, although born just yesterday, extends its reach every day, it is because it replaces long tables of numbers and it allows one not only to embrace at glance the series of phenomena, but also to signal the correspondences or anomalies, to find the causes, to identify the laws."
"Visualization is simply the creation of a strong mental image of the thing desired, the perfecting it each day until it becomes almost as clear as an existing material thing."
"Within the atom occur phenomena concerning which visualization is futile, to which common sense, the guidance from our everyday experience, has no application, which yield to studies by equations that have no meaning except that they work."
"Our intellectual powers are rather geared to master static relations and that our powers to visualize processes evolving in time are relatively poorly developed. For that reason we should do (as wise programmers aware of our limitations) our utmost to shorten the conceptual gap between the static program and the dynamic process, to make the correspondence between the program (spread out in text space) and the process (spread out in time) as trivial as possible."
