What is the first step in formulating a strong thesis statement for a research paper?
Your thesis statment is your claim for the paper. As such, it is important to make a claim that is debatable, meaning that it does not have an obvious answer. While the claim does not have to be revolutionary, it nevertheless must have some openness to it such that there is likely to be a reason to argue for your specific claim. At the same time, however, you must be certain that it is a defensible claim and does not require too much speculation and assumption on your part. Though finding this middle groun can be tricky, it is often a matter of understanding what your research, or the research that you rely on to make your case, actually shows. Typically research will suggest a claim that neither is too broad and vague, nor too narrow and obvious. Thus, figuring out what the research shows is the first step to formulating a strong thesis statement.
What is Kant's "Categorical Imperative" and what role does it have in his Moral Theory?
Kant's "Categorical Imperative" states that one must act only on the maxim which they can will to become a universal law. This means that one should only do an action if they could will that everyone in the same situation would also do that action. If you cannot will this, then you should not complete the action. Kant gives an example of theft. If everyone were to steal, then private property will no longer exist, without which, the very concept of stealing becomes illogical.
Which human ancestor was the first to create and use tools? How did this impact modern humans?
The first human ancestor to use tools was Homo Habilis which lived around two million years ago. Through scavaging and tool-building, Homo Habilis was better able to adapt to the environment and find food sources that other animals were unable to use. This allowed Homo Habilis to "out-compete" the competition and pass on its DNA that would ultimately lend itself to modern day Homo Sapiens.
