About us

Welcome to the Toronto Philosophy Meetup! This is a community (online and in-person) for anyone interested in philosophy, including newcomers to the subject. We host discussions, talks, reading groups, pub nights, debates, and other events on an inclusive range of topics and perspectives in philosophy, drawing from an array of materials (e.g. philosophical writings, for the most part, but also movies, literature, history, science, art, podcasts, poetry, current events, ethnographies, and whatever else seems good.)

Anyone is welcomed to host philosophy-related events here. We also welcome speakers and collaborations with other groups.

Join us at an event soon for friendship, cooperative discourse, and mental exercise!

You can also follow us on Facebook, Twitter or Bluesky and join our new Discord for discussion and to stay in touch with other members.

(🚨🚨🚨 WARNING: FRADULENT EMAILS are circulating that IMPERSONATE organizers of this group and ask you for money or personal information if you engage. IF YOU HAVE RECEIVED SUCH AN EMAIL OR IF YOU ARE UNCERTAIN about any message claiming to represent this group, PLEASE REPORT IT by contacting the main organizer Darren directly through Meetup's messaging system or other known channels. Watch out for scams in general, which are everywhere these days and easy to generate because of A.I. 🚨🚨🚨)

Feel free to propose meetup topics (you can do this on the Message Boards), and please contact us if you would like to be a speaker or host an event.

(Note: Most of our events are currently online because of the pandemic.)

"Philosophy is not a theory but an activity." 
— from "Tractatus Logico-Philosophicus", Wittgenstein

"Discourse cheers us to companionable
reflection. Such reflection neither 
parades polemical opinions nor does it 
tolerate complaisant agreement. The sail 
of thinking keeps trimmed hard to the 
wind of the matter."
— from "On the Experience of Thinking", Heidegger

"How Reward, Fear, and Salience Shape the Synapses of Memory"

We have spent considerable time discussing memory from the perspective of synaptic plasticity, Long-Term Potentiation (LTP), Long-Term Depression (LTD), declarative memory, and the hippocampus. Yet an important question remains:

Why do some experiences become unforgettable while others disappear almost immediately?

The answer appears to lie in the relationship between emotion and memory. Human beings do not remember all experiences equally. Events associated with fear, joy, love, reward, grief, embarrassment, novelty, or danger are often remembered with extraordinary persistence.

Neuroscience increasingly suggests that emotional systems influence which experiences are selected, strengthened, consolidated, and ultimately stored in long-term memory.

In this meet-up, we will examine how emotional processing interacts with the molecular and cellular mechanisms responsible for learning and memory. Particular attention will be given to the role of the amygdala, hippocampus, dopaminergic pathways, stress hormones, and neuromodulatory systems that influence synaptic plasticity.

Topics will include:

• Declarative and emotional memory
• The hippocampus and memory consolidation
• The amygdala as a detector of emotional significance
• Fear, reward, novelty, and salience
• Dopamine and the valuation of experience
• Norepinephrine and attention
• Stress hormones, cortisol, and memory formation
• Long-Term Potentiation (LTP) and emotional enhancement of synaptic strength
• Calcium signaling, protein kinases, CREB, and gene expression
• Why emotionally charged events become "flashbulb memories"
• The evolutionary significance of emotional memory

A central theme of the discussion will be that emotions are not merely feelings accompanying memory. Rather, emotional systems may function as biological mechanisms that determine which experiences are important enough to justify the metabolic cost of long-term storage.

From this perspective, memory is not simply a recording device. The brain is constantly evaluating experiences and asking:

"What is worth remembering?"

By exploring the intersection of emotion, neurobiology, and molecular signaling, we can gain a deeper mechanistic understanding of how experience becomes memory and how memory, in turn, shapes future behavior.

No prior neuroscience background is required. Participants interested in philosophy of mind, psychology, neuroscience, learning, behavior, and human nature are especially welcome.
