What astonished me was the very low toxicity of a substance that has such very great physiological power. A little pinch, 5 mg, every day, is enough to keep a person from dying of pellagra, but it is so lacking in toxicity that ten thousand times as much can be taken without harm.
I think it would be folly to expect that women will ever dominate or even approach equal representation in a large number of areas simply because their aptitudes, abilities and interests are different for physiological reasons.tony abbott
The powers, aspirations, and mission of man are such as to raise the study of his origin and nature, inevitably and by the very necessity of the case, from the mere physiological to the psychological stage of scientific operations.richard owen
Formerly character proved a strong curb for passions; in the present there is not much strength in character, and it grows less and less because of the prevailing scepticism, which is a decomposing element. It is like a bacillus breeding in the human soul; it destroys the resistant power against the physiological craving of the nerves, of nerves diseased. The modern man is conscious of everything, and cannot find a remedy against anything.henryk sienkiewicz
Whenever a man talks he lies, and so far as he talks to himself — that is to say, so far as he thinks, knowing that he thinks — he lies to himself. The only truth in human life is that which is physiological. Speech — this thing that they call a social product — was made for lying.Miguel de Unamuno
To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one have already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our dis -beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of their possessor's body at the time.william james
Psychology must postulate uniformity of interrelation of physical, physiological, and psychic processes.boris sidis
Snake virus is a natural secretion provided for the distinct physiological purpose of enabling the reptile to secure its prey.
When one turns to psychological models of mental illness, one finds that the psychodynamic model of human mind and of mental disease is also of considerable antiquity. Thus, Empedocles of Agrigentum (490-430 B.C.) from whom Hippocrates took the theory of four elements, stressed the importance of emotions of love and hate as the controlling agents of human behavior and of physiological functions.
Plato (427-347 B.C.) in his philosophical writings, stressed the inner psychological reality in contrast to the reality of the external world. He believed that the human soul consists of three parts. 1) The rational soul, which resided in the brain. 2) The anima soul, controlling emotions and passions, was located in the chest. 3) The vegetative soul, controlling physiological needs, was located in the abdomen, When dreams occurred in sleep, the irrational soul reasserted themselves.
That the variations are controlled by physiological law, we have now experimental proof; but that this control is guided ever so little in response to the needs of adaptation there is not the smallest sign.
It appears from this inquiry that color and other physiological characters are of a more superficial and accidental nature than was at one time supposed.
The psycho-physiological hypothesis is both inductively and deductively the sine qua non of the science of psychology.boris sidis
For art to exist, for any sort of aesthetic activity or perception to exist , a certain physiological precondition is indispensable; intoxication . Intoxication must first have heightened the excitability of the entire machine: no art results before that happens.
A quarter of America is a dramatic , tense , violent country , exploding with contradictions, full of brutal , physiological vitality , and that is the America that I have really loved and love . But a good half of it is a country of boredom , emptiness , monotony , brainless production , and brainless consumption , and this is the American inferno .
