Senses are physiological capacities of organisms that provide data for perception. The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive psychology (or cognitive science), and philosophy of perception. The nervous system has a specific sensory system or organ, dedicated to each sense.

Human beings have a multitude of senses. Sight (ophthalmoception), hearing (audioception), taste (gustaoception), smell (olfacoception or olfacception), and touch (tactioception) are the five traditionally recognized. Whilst the ability to detect other stimuli beyond those governed by the traditional senses exists, including temperature (thermoception), kinesthetic sense (proprioception), pain (nociception), balance (equilibrioception), acceleration (kinesthesioception), and various internal stimuli (e.g. the different chemoreceptors for detecting salt and carbon dioxide concentrations in the blood), only a small number of these can safely be classified as separate senses in and of themselves. What constitutes a sense is a matter of some debate, leading to difficulties in defining what exactly a sense is.

Animals also have receptors to sense the world around them, with degrees of capability varying greatly between species. Humans have a comparatively weak sense of smell, whilst some animals may lack one or more of the traditional five senses. Some animals may also intake and interpret sensory stimuli in very different ways. Some species of animals are able to sense the world in a way that humans cannot, with some species able to sense electrical and magnetic fields, and detect water pressure and currents.

Famous quotes containing the word sense:

    The term clinical depression finds its way into too many conversations these days. One has a sense that a catastrophe has occurred in the psychic landscape.
    Leonard Cohen (b. 1934)

    I don’t like your miserable lonely single “front name.” It is so limited, so meagre; it has no versatility; it is weighted down with the sense of responsibility; it is worn threadbare with much use; it is as bad as having only one jacket and one hat; it is like having only one relation, one blood relation, in the world. Never set a child afloat on the flat sea of life with only one sail to catch the wind.
    —D.H. (David Herbert)

    Have a sense of piety ever on your mind, and be ever mindful that this is subject to no change, but will last you as long as life and support you in death. Elevate your soul by prayer and by contemplation without mystical enthusiasm.
    James Boswell (1740–1795)
