Submission is now open for proposals for symposia to be presented at theBSPS2025 Annual Conference in Glasgow on 15^th -17^th July 2025. The deadline for submitting symposium proposals is *24^th January 2025*. *Overview* A symposium should involve several presenters, typically 3-4, organised around a topic of interest. Symposia may be on any topic in the philosophy of science. A maximum of 90 minutes of space on the programme will be allocated to successful symposia. The symposia will be selected by theBSPScommittee. The committee will strive for quality, variety, innovation, and diversity on the programme; ideally the programme will reflect the full range of current work in the philosophy of science. Priority will be given to symposia featuring at least one early career scholar. For the purposes of this call, a person is an early career scholar if at least one of the following criteria apply: (i) they are a PhD student; (ii) their PhD was awarded no more than five years ago (excluding any career breaks); (iii) they have never held a permanent academic position. Symposia that make connections with, or include, working scientists are warmly invited. We will not consider ‘Author Meets Critics’ sessions, but topical sessions that build upon recently published books are acceptable. Current members of theBSPScommittee may not feature in symposia, whether as organisers, presenters or non-presenting co-authors. *Instructions* Proposals must include sufficient supporting material to permit the committee to evaluate the quality and interest of the symposium. Proposals for symposia should include: * The title of the proposed symposium * A short descriptive summary of the proposal (100-200 words) * A description of the topic and a justification of its current importance to the discipline (500-1000 words) * Titles and abstracts of all papers, with 250-500 words for the title and abstract of each paper * A list of participants and either an abbreviated curriculum vitae or short biographical description (not to exceed 1 page) for each participant, including any non-presenting co-authors. * Institutional affiliation and e-mail addresses for all participants, including any non-presenting co-authors. * A note indicating which, if any, participants are early career scholars. *Deadline and dates* The deadline for submitting symposium proposals is *24^th January 2025*. Authors will be informed of the committee’s decisions around 14^th February 2025. Please see important information below onBSPSpolicy regarding multiple submissions. *Submission* Proposals for symposia should be submitted via email as one pdf file to the programme organiser, Ali Boyle (a.boyle2@lse.ac.uk <mailto:a.boyle2@lse.ac.uk>). *Rules for Acceptance* No one will be permitted to present more than once atBSPS2025. Thus, if a symposium proposal in which you are a presenting author is accepted, you may not submit a contributed paper for which you are the presenting author. Commentators that are part of symposia are considered to be presenting authors. A scholar may appear as co-author on more than one paper or symposium talk, but may present atBSPS2025 only once. Any individual can be part of only one symposium proposal in which they are a presenting author. Note that this policy excludes the practice of being a presenting author for more than one symposium proposal and subsequently choosing to present in only one symposium if multiple proposals are accepted. If an accepted symposium subsequently loses participants, maintaining acceptance will become contingent upon the symposium organiser developing satisfactory alternatives to maintain the quality and coherence of the committee. All questions about submissions should be directed in the first instance to the programme organiser, Ali Boyle (a.boyle2@lse.ac.uk <mailto:a.boyle2@lse.ac.uk>).
