Adverb
By infinitesimals; in infinitely small quantities; in an infinitesimal degree.
Source: Webster's dictionarySince space is continuous, it follows that there must be an immediate community of feeling between parts of mind infinitesimally close together. Without this, I believe it would have been impossible for any co-ordination to be established in the action of the nerve-matter of one brain. Charles Sanders Peirce
Accordingly, time logically supposes a continuous range of intensity of feeling. It follows then, from the definition of continuity, that when any particular kind of feeling is present, an infinitesimal continuum of all feelings differing infinitesimally from that, is present. Charles Sanders Peirce
How can a past idea be present?... it can only be going, infinitesimally past, less past than any assignable past date. We are thus brought to the conclusion that the present is connected to the past by a series of real infinitesimal steps. Charles Sanders Peirce
During my slumber I had a dream. I thought I was once more by the side of the Sphere, whose lustrous hue betokened that he had exchanged his wrath against me for perfect placability. We were moving together towards a bright but infinitesimally small Point, to which my Master directed my attention. Edwin Abbott Abbott
What people ought to be asking me is "Where do you get those tiny, little infinitesimally faint sparks that you then somehow manage to blow up into ideas?" Of course, my answer would be, "I have no inkling whatsoever." Caitlín R. Kiernan
The chances of each of us coming into existence are infinitesimally small, and even though we shall all die some day, we should count ourselves fantastically lucky to get our decades in the sun. Richard Dawkins
