Hence, even in the domain of natural science the aid of the experimental method becomes indispensable whenever the problem set is the analysis of transient and impermanent phenomena, and not merely the observation of persistent and relatively constant objects.

From the standpoint of observation, then, we must regard it as a highly probable hypothesis that the beginnings of the mental life date from as far back as the beginnings of life at large.

Now, there are a very large number of bodily movements, having their source in our nervous system, that do not possess the character of conscious actions.

The distinguishing characteristics of mind are of a subjective sort; we know them only from the contents of our own consciousness.

The task of physiological psychology remains the same in the analysis of ideas that it was in the investigation of sensations: to act as mediator between the neighbouring sciences of physiology and psychology.

Hence, even in the domain of natural science the aid of the experimental method becomes indispensable whenever the problem set is the analysis of transient and impermanent phenomena, and not merely the observation of persistent and relatively constant objects.

Child psychology and animal psychology are of relatively slight importance, as compared with the sciences which deal with the corresponding physiological problems of ontogeny and phylogeny.

We speak of virtue, honour, reason; but our thought does not translate any one of these concepts into a substance.

Physiological psychology, on the other hand, is competent to investigate the relations that hold between the processes of the physical and those of the mental life.

On the other hand, ethnic psychology must always come to the assistance of individual psychology, when the developmental forms of the complex mental processes are in question.

The general statement that the mental faculties are class concepts, belonging to descriptive psychology, relieves us of the necessity of discussing them and their significance at the present stage of our inquiry.

Physiology seeks to derive the processes in our own nervous system from general physical forces, without considering whether these processes are or are not accompanied by processes of consciousness.

Physiological psychology is, therefore, first of all psychology.

In the animal world, on the other hand, the process of evolution is characterised by the progressive discrimination of the animal and vegetative functions, and a consequent differentiation of these two great provinces into their separate departments.

Hence, wherever we meet with vital phenomena that present the two aspects, physical and psychical there naturally arises a question as to the relations in which these aspects stand to each other.

The results of ethnic psychology constitute, at the same time, our chief source of information regarding the general psychology of the complex mental processes.

Physiology is concerned with all those phenomena of life that present them selves to us in sense perception as bodily processes, and accordingly form part of that total environment which we name the external world.

In Aristotle the mind, regarded as the principle of life, divides into nutrition, sensation, and faculty of thought, corresponding to the inner most important stages in the succession of vital phenomena.

The materialistic point of view in psychology can claim, at best, only the value of an heuristic hypothesis.

Philosophical reflection could not leave the relation of mind and spirit in the obscurity which had satisfied the needs of the naive consciousness.

Physiology and psychology cover, between them, the field of vital phenomena; they deal with the facts of life at large, and in particular with the facts of human life.

The attitude of physiological psychology to sensations and feelings, considered as psychical elements, is, naturally, the attitude of psychology at large.

From the standpoint of observation, then, we must regard it as a highly probable hypothesis that the beginnings of the mental life date from as far back as the beginnings of life at large.

A true critic ought to dwell upon excellencies rather than imperfections, to discover the concealed beauties of a writer, and communicate to the world such things as are worth their observation.

From the very commencement the student should set out to witness the progress and effects of sickness and ought to persevere in the daily observation of disease during the whole period of his studies.

The power of accurate observation is commonly called cynicism by those who have not got it.

It's a great mistake, I think, to put children off with falsehoods and nonsense, when their growing powers of observation and discrimination excite in them a desire to know about things.

Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.

Rhetoric and dialectics can't change what I have learned from observation and experience.

By means of microscopic observation and astronomical projection the lotus flower can become the foundation for an entire theory of the universe and an agent whereby we may perceive Truth.

Much of my work in this period was concerned with exploring the logic of economic models, but also with attempting to reconcile the models with every day observation.

There's certainly nothing original about the observation that conscious experience poses a hard problem.

The five steps in teaching an employee new skills are preparation, explanation, showing, observation and supervision.

Observation is a passive science, experimentation an active science.

Children have very sharp powers of observation - probably sharper than adults - yet at the same time their emotional reactions are murky and much more primitive.

Now the identification of individual sounds by phonetic observation is an artificial way of proceeding.

It is a common observation, that the more solicitous any people are about dress, the more effeminate they are.

There is no more difficult art to acquire than the art of observation, and for some men it is quite as difficult to record an observation in brief and plain language.

Laws and customs may be creative of vice; and should be therefore perpetually under process of observation and correction: but laws and customs cannot be creative of virtue: they may encourage and help to preserve it; but they cannot originate it.

If you make listening and observation your occupation you will gain much more than you can by talk.

My observation is that women are merely waiting for their husbands to assume leadership.

The Artist is he who detects and applies the law from observation of the works of Genius, whether of man or Nature. The Artisan is he who merely applies the rules which others have detected.

We are told that the first part of the process is to select the very smallest seeds from the smallest plants, which is not at all unlikely, but I cannot speak to the fact from my own observation.

The ultimate court of appeal is observation and experiment... not authority.

But what is of great importance to me is observation of the movement of colors.

Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.

My observation is that after one hundred and twenty years of modernisation since the opening of the country, present-day Japan is split between two opposite poles of ambiguity.

The lesson of the last year is this: foreign policy can't be managed through the politics of personality, and our President would do well to take note of an observation John F. Kennedy made once he was in office - that all of the world's problems aren't his predecessor's fault.

One man's observation is another man's closed book or flight of fancy.
