It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. (61) You either have science or you don’t, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits.The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. (62) It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering the way ahead seems. (63) It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. (64) It is not so bad being ignorant if you are totally ignorant the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not so bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.But we are making a beginning and there ought to be some satisfaction. There are probably no questions we can think up that can’t be answered, sooner or later, including even the matter of consciousness. (65) To be sure, there may well be questions we can’t think up, ever, and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers if we keep at it long enough, and pay attention. To be sure, there may well be questions we can’t think up, ever, and therefore limits to the reach of human intellect, but that is another matter.
Welcome to physiology 100. I’m Dr. Ann Roberts. I assume everyone here is the sophomore since this is the Nursing Department Second Year Physiology Course. If you are first year nursing students, please see me after class about transferring to the introductory course. OK, I’d like to begin my first lecture by introducing two important terms: Vitalism versus Mechanism. How many of you’ve heard these terms Oh, I see someone of you have! Well, vitalism and mechanism are two completely opposite approaches to human physiology. According to the vitalist, the laws of the physics and the chemistry alone cannot explain the processes of the life. To the vitalist, there is a so called "vital force" and this "vital force" is totally separated from matter of energy. As you may have guessed, vitalism is a kind of philosophical approach. Mechanism, on the other hand, is the view that all life phenomena, no matter how complex, can be explained according to chemical and physical laws, since we can support mechanism through scientific experimentation. The modern scientist tends to be a mechanist, but vitalism is not totally dismissed especially in field, such as brain physiology where terms such as human consciousness, haven’t been defined in physical and the chemical terms. I recently read an interesting article that deals with the very question. Is the mind separated from the brain or is the mind only the chemical and physiological working of the brain I’d like to continue with this next time so that we can speak more details. I have some copies of that article and I want to take it with you and read it for next week. For whom is the lecture intended
