Comparative to the commonplace focus onto developments in mathematics and physics, the life sciences appear to have received relatively sparse attention within the early history of analytic philosophy. This paper addresses two related aspects of this phenomenon. On the one hand, it asks: to the extent that the significance of the life sciences was indeed downplayed by early analytic philosophers, why was this the case? An answer to this question may be found in Bertrand Russell\'s 1914 discussions of the relation between biology and philosophy. Contrary to received views of the history of analytic philosophy, Russell presented his own \'logical atomism\' in opposition not only to British Idealism, but also to \'evolutionism\'. On the other hand, I will question whether this purported neglect of the life sciences does indeed accurately characterise the history of analytic philosophy. In answering this, I turn first to Susan Stebbing\'s criticisms of Russell\'s overlooking of biology, her influence on J.H. Woodger, and her critical discussion of T.H. Huxley\'s and C.H. Waddington\'s application of evolutionary views to philosophical questions. I then discuss the case of Moritz Schlick, whose evolutionist philosophy has been overlooked within recent debates concerning Logical Empiricism\'s relation to the philosophy of biology.

I first met Dr. Russell in the Fall of 2000 at the Massachusetts General Hospital (MGH). I entered the Russell-Round-Room which was packed with surgeons and physicians of MGH, among whom there was no shortage of self-esteem. I came across a handsome man, full of vigor and competence, standing still for nearly two hours in the corner of the room near the blackboard. He was remarkably attentive to the questions, for which he had very concise responses. He was soft-spoken with an inviting smile, and had a welcoming, modest air about him. Despite his remarkable academic achievements, he was strikingly unassuming and serene -- features likely ingrained in his very nature.

Plasma cells known as \"Mott cells\" present non-secretable accumulations of immunoglobulins called \"Russell bodies\". Its presence is related to hematological neoplasms, but it can appear in chronic inflammatory processes. The most common occurrence within the digestive tract is the gastric antrum associated with H. pylori infection. Our patient is added the rare extragastric cases where the association with H. pylori is inconsistent. We have found a frequent appearance of lower digestive and urological neoplasms in relation to these cases, justified by the expression of circulating cytokines in the tumor area that lead to the overactivation of plasma cells. This possible association could lead us to know data about the tumor environment and serve us for early diagnosis or future therapeutic targets.

John Bowlby\'s attachment theory has made a lasting contribution to scientific understanding of the nature and the impact of close interpersonal bonds, tracing their influence from early childhood through adulthood and into bereavement. The experience of separation and loss featured powerfully in Bowlby\'s account of the causes of mental health difficulties. He acknowledged many sources for his ideas. However, one potential intellectual force, namely, that of the eminent philosopher Bertrand Russell, is missing. The association between Bowlby and Russell is highlighted in this essay to illustrate how a monumental theory may emerge from ideas already around during a particular historical period. Scientific and personal features of their lives are explored to shed light on possible influence. Commonalities between their propositions about attachment are described as well as pertinent biographical details. Questions whether Bowlby was aware of Russell\'s writing on this topic and reasons why Russell\'s ideas were not acknowledged are considered.
